Biometrics appointment impossible

Hi,

While I am presettled, my wife (of European citizen) needs to do biometrics.

I read such optimistic dates in forum, stating that they managed biometrics same or next day after they applied --- but we do not see ANY free appointment time slots. My wife checks daily, there is even no free appointment around Manchester for £100, we see only the London lounge for £200.

After mid-June, her application will expire only because there are no free slots, at Settled Status
Is there any other way to make the biometrics?

Thank you...
