Late last night we started receiving reports from you fine folks that you were encountering issues syncing with iCloud in 1Password for iOS. First, let me say we're really sorry about the trouble you're having if you've encountered this. I started investigating as soon as I heard about it this morning and here's what I was able to gather.
We didn't change anything in 1Password last night, but we also don’t have all the information we need to reliably determine where the problem lies. We are in contact with Apple while investigating the issue. It presents itself differently depending on a few things:
1Password for Mac seems to sync properly to other Macs. It's only 1Password for iOS that is affected by this.
The error in the log files seems to indicate that 1Password 5 for iOS no longer has permission to access the CloudKit container (the place we sync to in iCloud). We didn't change anything in the CloudKit control panel, so it wasn't caused by us directly as far as we can tell.
Alternative sync solutions like Wi-Fi Sync and Dropbox continue to function. Again, this issue only affects iCloud syncing in 1Password for iOS. We can assist you in getting things switched over if you would like some help.
I've filed a report with Apple, and I'm awaiting information from them to either tell where we went wrong or that it's something on their side. We'll update you all here as we learn more. You can subscribe to email updates about this issue by clicking the star in the upper right:
