I don't have the problem the OP mentioned, but I do have the one mentioned by Skylain. Mine randomly reset after using it mostly without issue for about 36 hours, (it was after I turned my phone back on after it ran out of batteries overnight, so that might be related). Thankfully I'd saved my emergency removal password, so I removed it from my account and have not put it back. I left a review to this effect on the product page in the google play store, and I saw several other reviews by people with the same problem. The app doesn't cost anything, so I suspect that if it ever gets fixed, it won't be until they've dealt with other issues in other areas of the game first. :/ I wish they'd fix it, I want to use it. I'd even be willing to pay like 1 or 2 dollars for it if it meant we'd get better support for it and sooner fixes. Better than the 11 dollars or whatever the physical token is.
