In my case I could continue to use the app, it broke the ability to sign into the vault. If you only lock your vault and not fully logout you may not have noticed it.

Thanks. I do not even lock BW, not to mention logging out, and almost never connect to the vault via the web interface - so yes I must have simply missed it.
I did not notice anything, maybe the break happened during the night in Europe. Or the Android app did not want about problems.
