Cursor tab won't work when focus during the free trial

I’m new to cursor, but is this normal? when focus on a blank line, cursor gives nothing, I must press ctrl+k to enter some instructions to get it work.

Hey @xnscu

Do you want to use autocompletion?
First, check if this feature is turned on.

Secondly, how long have you been using the free plan? Maybe your quota has been exhausted, as the free plan only gives you 2000 autocompletions.
