Thank you @Pratyush Sharma,
If you know it, it's totally easy!
You were 100% right. The DownloadSource was the reason. I had Installed from AppStore not with Web-Download.
Thank you very much for help!
Because you are batched by «ENPASS TEAM» some following question/thoughts:
Why there are differences although the version-identifiers (6.6.0) is the same?
Normally, the app from AppStore seams to be «more secure».
Would be great, the differences from AppStore <-> WebDownloadwere be published.
Currently without SHA/MD5 hash without knowing there are differences (same version in the install-overview), I would always prefer the AppStore «by default».
Maybe this will help other on the same way, searching the difference between documentation/realLive.
Best regards
Martin
