Home button, arrows… well none of them works. Doing the same in the “more” app works
I even tried yatse on another phone… same issue.

It’s covered in the FAQ 
You have an issue with Event Server on Kodi side, reconfigure Kodi correctly or disable the Event Server usage in Yatse by editing your host.
ah… I deleted the host in settings and added it again. Now it works as expected. Thanks.
