Before I had a problem with beginning the whole thing, but now with account emails finally matching and everything, originally after that everything was going fine. Then one day, everything suddenly stopped syncing. I will continue to read the book on my phone, but going to my tablet, I find it not going to right place or even asking me if I want to go to the place I left off, and I have to go back a few pages on my phone to even find out what chapter I'm on. I don't know what changed, there was no attempt to change anything before then, at least not on my part; I checked the accounts and between phone and tablet everything matched, both Overdrive and Adobe ID, so I don't know what the problem could be this time around. Please, if anyone could help, it would be greatly appreciated!
