Description
This issue seems to be limited to iOS 8.4.1. I couldn't reproduce it on any newer version.
Environment
iOS 8.4.1
iPhone 5s
ABB 1.2.1 to 1.3.1
How to reproduce
- Install ABB 1.2.1
- Open ABB and browse a few websites to gather history data
- Go to the App Store and install ABB 1.3.1
- Open ABB
Observed behaviour
A error message is shown saying "User data migration failed: Can't find model for source store. Data will be cleared." and all custom data (history, bookmarks, settings) is deleted.
Expected behaviour
No error message is shown and no custom data is deleted.
