I can't be the only one with a sad story I activated my 2fas to one of my accounts it worked a couple of times and stopped working I have the code and QR code but still no access.

Came back to this app after years only to find the codes are gone and back up not working

I just can't use this inadequate garbage anymore that they don't bother to make basic improvements on. Can stupidly only delete one at a time, no multi selection. And Google Drive synch is trash, always synchs wrong way. Can't even take a QR code photo of all tokens to save on other device. Its taking me 3 hours to do what should be a basic task, baking up like 4 mere kb of data to another phone. Absurd
