Your application is in background checks (times vary from a week to 2 months) but hopefully thats a sign your app is progressing. Expect a correspondence letter stating biometric validity which will be a signal your app has been concluded, hopefully followed by a Passport request.
I've read a lot about this biometrics validity letter, what is this btw? I did my biometrics when I submitted my paper application and it does say online:
biometrics enrollment date, enrollment number, and expiry...
and ya hopefully it's soon since classes are set to begin in about 7 weeks....
