I successfully installed the new version of the app, was able to link it using the code (wasn't sure about the google linking so followed what I understood the instructions were). I was able to log into my account, all fine. Logged out, switched user, attempted to do the same with the alternate user: the updated logo appeared but it wouldn't launch. While it appears that the app is installed for all profiles, the app gives the error on launch for both my main account and the mini, "download failed because you may not have purchased this app". Rebooted phone, same errors. Nexus6 (2015). I haven't been able to find a workaround yet. So yeah, it's a free app so payment isn't required. The error message isn't helping at any rate. Possibly multi accounts are banned? I don't know, never did find TOS when I setup the mini during mini rumble days.
