The client and plugin are all from the latest SDK version 70.5.2 (when I go to the Android client "About" it shows 70.5.1 but I installed the 70.5.2 version, I guess this is another "bug")
The server is still in SP03, but I will try in SP04 later today, if I get the same behavior I will create an incident. But I don't think this issue should be affected by the server version.
