@markushub thanks for the report! No luck these times, huh? @stefan-niedermann will be at my place in an hour or so, I'll force him to fix this.

Your server has not been connected successfully - Please try to clear the storage of the app and reimport your account as described here.

Hint @desperateCoder - no server app version at the stacktrace instead of 0.6.4 in the current version.

[stefan-niedermann]

@markushub did clearing the storage and reimporting the account work for you or are you experiencing the same issue?

[markushub]

thank you. Clearing the storage and reimporting the account solves the problem

[stefan-niedermann]

Thanks for the feedback!
