Marvin 3 Not Syncing iPad Pro & iPhone XR
#1  LUEBECKER 11-09-2019, 08:20 AM
In Marvin 3 sync mode my iPhone XR doesn't see my iPad Pro and vice versa. This started with iOS 13.2.1 and I've just updated to iOS 13.2.2 with no change. I've been using Marvin 3 for quite a while and never saw this before. The iPhone only sees itself in Sync and the same for the iPad. I'm signed in to iCloud and iCloud sees Marvin. Don't know what else to do. Anyone have any suggestions?

I haven't seen this issue. Although Marvin hasn't changed and iOS has, I'd suspect iOS broke something. Perhaps someone on the iOS forum could explain what has changed?? If you do figure it out, please let us know.

Have you double checked to make sure iCloud is enabled for Marvin (not the Cloud Picker but via Settings -> iCloud Account -> iCloud)?

Just tried on mine and all devices show when I do a manual sync:

Yes, Marvin is enabled in my iCloud settings, and if I go to iCloud settings on my Windows Desktop, under storage iCloud tells me that i have 3.6 MB of Marvin data stored there. When I click Sync on my iPhone, I'm only seeing my iPhone and not my iPad as well. And the same thing happens on my iPad, only the iPad is shown in Sync mode. I have no idea what's going on. Marvin is working well otherwise.

Hey LUEBECKER,

Not Marvin but BookFusion has been updated to support iOS 13. BookFusion is a cross platform eBook app that allows you to upload, organize and read your eBooks across all devices. BookFusion supports all eBook formats including epub, mobi, PDF, and comic (cbr/cbz) formats. Reading HTML, txt, or rtf/doc (Uploads via the web interface).

All your bookmarks, highlights, comments and reading progress will always be synced across all devices. We also have a Calibre plugin that makes sending your eBooks from Calibre as seamless as possible.

iOS App: https://itunes.apple.com/us/app/bookfusion/id1141834096

Please take us for a spin and let me know if you have any feedback.

Thanks for the info skillachie - but this is the Marvin thread....and it is pretty bad form to advertise for yourself or your company here...if not outright breaking the MR rules.

Hum, that's odd. I have an iPad Pro and iPad mini with Marvin, both with the latest and greatest iOS. No problems syncing. One possibility is how you get the book in to Marvin on the two devices. I had a similar problem several years ago (2016 when Marvin 3.0 came out) and basically, if I recall correctly (it has been a while) the way Marvin creates the hash values that it uses to sync can differ if the book is imported into Marvin differently. You might try as an experiment, load a book into marvin on one device, scroll a few pages and then sync. Then load the exact same book into marvin on the other device in exactly the same way, sync it and see if you see the other device. I typically only see one device unless I've synced the same book on both devices.

The "are you sure it's plugged in" question (anyone who has done tech support has had to ask that question at least once), is are you really sure you are using the exact same iCloud account on both devices? It's not as straight forward as you might think.

Hash value is just md5 checksum (I investigated the m3backup file that Marvin 3 generates for backup/restore).

If the files are binary identical (e.g. copied via Dropbox), then they should be recognized as the same book.

Alas, if these were transferred via Calibre OPDS server or Calibre Companion for example, they could differ since Calibre updates metadata when sending books to devices (ergo modifying the EPUB and checksum). It's possible that the same book downloaded at two different times (say 2 months apart) from the Calibre content server would have different checksums.

Hey Turtle91,

The reason is because the last time Marvin was updated was in 2017. The only reason I made the comment was to make the user aware of a potential alternative as Marvin appears to be abandoned. Other users have also made comments about other alternative apps due to the status of Marvin in Marvin related threads.

If it is a forum rule, I will gladly obey it but not sure if it is since even today there are comments inside Marvin threads talking about alternatives. Is it simply because I am apart of BookFusion?

A mod would be the one to decide on a ruling but I think the numerous posts fall into #6, relevant but ubiquitous.
