Elite qubo Smart b+ trainer

I’ve used the trainer with the Elite application and a while back also with Zwift and it was good. I resubscribed to Zwift recently but now find the resistance way too high. I have to pedal hard even on downhill routes! The tyre also squeals on the roller so its just unworkable, Has anyone else had the issue or currently using this trainer successfully?

Does calibrating it do anything? I think this might be the process… https://elitesrl.zendesk.com/hc/en-us/articles/360014523580-Qubo-Power-Mag-Smart-B-Aleno-Calibration

If you’re using a new trainer tire and it’s not working, I would contact Elite support.
