Thanks for the report @ahnafnafee. Unfortunately a payed subscription is needed.
Taking in consideration the provided screenshot and the description I'll move it to Needsdiagnosis for further investigation.
@softvision-oana-arbuzov thank you. My screenshot would be same as uploaded here, but I've got account so can do some basic testing if you want.

I had a trial HiFi account and encountered this issue. However it didn't cause any problem in Chrome.
Chrome works fine and even Tidal suggests to use it. Firefox doesn't work.
Note: For me even if I've selected HiFi>Standard, for a 30day free trial it asks for my credit card payment.

It does as it will charge you after free period ends. You need to stop subscription right after trying to avoid it. But if you are unsure, please don't try.
