I've run into a couple quirks on my Moto G XT1033..
The 1Password keyboard has 2 keys ( _ and < ) overlapping witht the spacebar (see images) - it appears as though the size of the spacebar is incorrect as it resizes when a key is pressed & then resets to the overlap position.
I migrated from 1Password4, and ever since, to unlock the mobile app i need to enter my account password, whereas for my pc i enter my original master password - is this by design? or a quirk of the migration from dropbox? or ?
edit: added mobile app version & typos
1Password Version: 6.4.5
Extension Version: Not Provided
OS Version: Windows 10, Android 6.0.1
Sync Type: Cloud
