There seems to be errors when syncing filtered decks between iOS and Mac after update to 2.1.29. Let’s say on a Mac a filtered deck is empty. On iOS I rebuild the deck and have some cards in it. When then syncing the filtered deck the deck on a Mac will remain empty. Only when I separately rebuild the deck on the Mac too, than changes will get synced. ---

This was a bug that has been fixed in the 2.1.30 beta 1 desktop and the 2.0.65 beta iOS apps. Looks like it should be fixed in the next stable release on each platform. ---
