Hello @mplorentz
I see tests are failing, but they are failing for all pull requests. Or should I also fix it?

Hi @RomanPodymov, thanks so much for the contribution. I'm sorry it's take so long to get back to you, we aren't working much on Planetary anymore.

I think you can ignore the test failures for these tests:

FeedStrategyTests.testPostsAlgorithm()
FeedStrategyTests.testPostsAndContactsAlgorithm()
FeedStrategyTests.testRecentlyActivePostsAndContactsAlgorithm()

They are also failing on main. However I am worried about this failing test:

AppConfigurationTests.test_archiving()

As that one has not failed on main, and I suspect it may be related to the changes to AppConfiguration+Data.swift. If you could take a look into that I would appreciate it. Otherwise I will look into it when I get time.
