This issue seems to be limited to iOS 8.4.1. I couldn't reproduce it on any newer version.


iOS 8.4.1
iPhone 5s
ABB 1.2.1 to 1.3.1

How to reproduce

  1. Install ABB 1.2.1
  2. Open ABB and browse a few websites to gather history data
  3. Go to the App Store and install ABB 1.3.1
  4. 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.

The cause is ios8 incapable of migrating a database consisting of (and merged from) two separate data models
