Hi @Pedro_Subtil and thanks for reaching out!
I took a look into your account and from what I can see you’re using an old type of space called “Personal Projects”. Unfortunately, we do not support Personal Projects anymore and recommend all our users to move to a personal Workspace instead. Here is a thread on this topic from the Forum: Differences between Personal Projects & other Workspaces (free version). So the best advice I can give you is to create a brand new Workspace in your account and to transfer all your projects from your Personal Projects to your new Workspace. You should have no problem using the Android widget.
PS: I’m moving this bug to #bugs:resolved-bugs since we don’t support this type of space anymore, but feel free to reach out if you have any follow-up questions!
