That was my feel with by Biometrics, it's not fun. Have you been able to setup your GCKey Account. I struggled with that too but eventually got it setup and linked my application to the account. This does give a slightly better status but may not answer all your questions. It will allow you to be more confident in out things move forward. For me, I needed to upload a document and before GCKey was setup, I had no idea if it was submitted correctly.
On the spreadsheets, everyone seems to progress at different speeds. but hopefully you can find someone in a similar circumstance that gives a more reasonable benchmark to check against.
Good luck!
