How to select band for EE

Hi, after the recent update I don’t have the option to select which band I want on the quick setup page. It has disappeared from the page? How can I tell which band I am using? It is LHG LTE Cat6 4g outdoor long range router. I am using an EE sim but it gets really slow in the evenings

I have a different model router but it may be the same. In Winbox if you select the LTE interface, on the General tab it should have options to select bands. If it doesn’t can you put up a couple of screenshots showing what you do have available?
