The app is the version on the Play store. It was installed today.
Android 9 is the newest version available for my phone. I'm not buying a new device to use this app. 🙂 I see posts fr om two years ago wh ere you say the app is going to be updated. I think I'll stay with Chrome Desktop.
I just found and installed the RU and 4 hosts today on Windows 10 PC's in my home. I have one Windows viewer and an Android viewer. The Windows viewer works fairly well.
The Android viewer does not work very well at all. I can connect once with the Internet-ID but if I try again I get an error, External exception 38. The connection info is not saved so I have to close the app and enter the ID every time I want to connect.
Another error I get is related to the non-existant address book, I guess.
I have attached both error screenshots.
The Android device is a Samsung S8+ phone with Android 9.
