Thanks to one of the users, I have managed to solve the problem that Sequle crashes on startup on some.
There is a fix for this while waiting for official fix to AppStore:
Connect to some network when starting sequle and it should start fine.
The app will crash if it’s not connected to any network. It’s not trying to call home, I just forgot to turn off network debugging (which was used during developing).
I’m sorry for the trouble. The fixed version is submitted for review already, however it might take time to process because of the holidays.
