Android Alpha Testers - one final test please

First of all thanks to everyone who involved themselves in the android alpha test, it caught loads of issues.

One of the big changes from v281 to v282 was adopting google's new sign-in credentials system for gdrive, and it has caused a whole load of issues that unfortunately we didn't pick up in alpha testing (it's just not working for some people).

As a result I'm reverting back to the old deprecated gdrive sign-in system for v284. I'll keep using that until they turn it off, as it is just much better.

I'm pretty sure that it is working, but to be sure, I've uploaded v284 to the android alpha test. If you're on the alpha program and have the time, please test using gdrive:

1) that you can access your gdrive files and open them.

2) you can save, copy etc to gdrive as you'd expect.

Please let me know here that it is working and after enough positives I'll release it to production.

As ever, thanks for your help and support.
