K-9 mail in play store has not been updated since 2018!
PLEASE enough pre-release already!
PLEASE choose one version and submit to Google already!
If you do not do so you will DIE!
I have been wanting to donate money to your project for years now only I cannot in conscience donate money to developers who REFUSE to release a product!
Good bad or otherwise put something up in the play store already.
I am using your current pre-release software now and it works just fine so please upload something to the play store already or at least provide everybody in the forum a valid excuse to why you refuse to do so.
