Excuse my English. I hope you understand. When I use k-9 on my tablet I use it in landscape mode. Than I can’t see in the left bottom ‘settings’ and ‘manage folders’. Is it possible to see these in landscape mode?
which version of K9 do you use? I tested on my tablet with version 6.30x and it worked well. Maybe best to add a screenshot here?
Thanks for your response. There has been an update and now it looks fine
