The android clients don't exist on play store[1][2]. And the client's website is also not reachable[3].

Wow, I have deedum on my android, but I can see it is no longer in the play store.

I wonder if that has to do with that app change google is trying in order to be a walled garden like Apple.

I hope the EU is still sticking it to google and that carries over to the US.
