I've been using this app in a big way for at least 18 months. I have around 3200 notes, which I was studying quite regularly on the "Long Term Study" schedule before the new iCloud sync implementation was rolled out. I create them all on my Mac and then studying them during walks, etc. on my phone. A usual study session would involve five to ten rounds of 20 cards on my iPhone. The scheduling feature seem to work as advertised, and it would eventually, over a few months, move through my entire stack, showing cards couldn't remember more frequently.

But since the rerelease of the app and the new iCloud sync implementation, I've encountered a lot of problems, which I've tolerated for months now, but have made it almost impossible to keep using this app.

i. The app on my iPhone is almost never satisfied that it's synced with iCloud. It will sync every chance it gets, even when I haven't used the Mac version, or made any changes or studied any cards whatsoever. When I have studied cards on my iPhone (with no other changes to my stacks either on the phone or Mac), it often takes hours to complete the sync, during which time I can't switch between apps because this will cause the syncing feature to "unexpectedly disable". So my phone is comatose for a couple of hours (every day) while it syncs the fact that I studied 200 cards. Is this normal behaviour?

ii. The other thing is, it no longer seems the "long term study" schedule is working properly, as it has been showing me the same set of cards for the past few weeks. I thought I wasn't studying them enough, so I study them everyday now, but the app seems to pick those same cards every day, leaving my 2800 other cards unseen.

I've tried many things to address this (including everything in the article on fixing the iCloud feature). In my case the iCloud does actually sync the cards, but it just takes far far too long for what one might reasonably expect. Most recently I've "reset the study schedule" for all cards across all my stacks. It doesn't appear to have made any difference, but I'm methodically keeping checks on scheduling dates and so forth, which I'll repost about if I see an improvement.

Could I please have your thoughts on these issues, and suggestions how I might fix them if there's something on my end that I can fix?

Thank you, Adam.
