After going through all the comments here, I am pretty sure its a glitch in the tool.
I received a biometrics letter on the 3rd of December 2019, and I submitted my biometrics on December 4th, 2019 at VFS Bangalore.
The same day under application information the Biometric ID, Submission date and Expiry date were updated.
However, under the home page, it still showed as "Action required".
The last date for biometric submission was January 3rd, 2020, after which the status changed to submitted, however, under the Biometrics tab in the portal it changed to "We have not received your fingerprints. Check your biometrics request message below for details".
Checked the validity of biometrics and it says it's valid.
But seeing all the messages here, I am pretty sure there is nothing I can do other than wait. And once I get my PR, it should change.
If anyone has a better idea please let me know.
Thanks!
