any reports of modifications date change in 1password beta 7?

I'd not previously noticed anything odd but when I saw your post I decided to check more closely—especially as I have a smart folder which shows items updated within the past month. (I should say I, too, am now using beta 8 on macOS 10.13.4 and using WLAN to sync to my iOS devices.)

There do appear to be one or two entries showing a modified date of 29th March (the morning after I'd first installed 1Password 7) which I certainly don't recall modifying. I'm guessing that was the time when I first synchronised 1Password 7 for Mac with my iOS devices—but can't be absolutely sure about that.

The oddity applies only to a very few items—notably, I think, some (but not all) secure notes. I've not got any oddities after that date (i.e., there are quite a few changes to the modified date but I know I've edited those items). I have regularly synchronised 1Password 7 for Mac to my iOS devices since that date—and should perhaps make clear that I only ever make changes on the Mac, and never on the iOS devices.

Sorry not to be more precise. Can you be any more precise about exactly what you see?
