Donation via Playstore in v4.0.0-beta1 seems to work.
Can somebody confirm that? 
Maybe. When I choose to donate by playstore I get a message “payback for the SMS we sent you”. When I click on that message I get a pop-up to pay €2
As far as I know, Google takes a big part of that, so what’s the best way to donate? Playstore or PayPal?
Hi @TuxICT if you have a PayPal account and you like to donate and also think OMEMO is important why not donate here:
https://www.bountysource.com/issues/18980767-pfs-otr-omemo-encryption
to push OMEMO implementation.
Maybe this way we can motivate another developer to support Kontalk

Unfortunately they both take something off the revenue. However Google is the most expensive one: they take 30%.
