If the account was created after this:
Then yes you will have to wait until November/December most likely.
Mirrors are done every 3-4 months, or unless they need it done before a mass test.
The last 3 mirrors were:
8/10/2021
6/1/2021
2/15/2021
The one for 8/10 was specifically right before a major mass test
So the next one could be end of Nov or early Dec.
