Yes, my sync appears to have stopped as well. It did this a couple of years ago, can't remember when. At that time it was because dropbox made changes to their api and pocket had to be updated. We got Tim's attention at that time and it was updated. I'm not so sure this time. May have to look for another app.
Looks like it's what I assumed. Dropbox updated their api again, on or around March 29. Pocket sync is broken, and unless we can get Tim's attention to update it, this app is done as far as sync. I see he hasn't posted here in a couple of years.
So.... what password manager is everyone switching to? I'm thinking of trying SafeInCloud but right now I don't have much time to deal with this.
