Trainer going straight into highest drag at start

Have new update installed today on Samsung S22+, then went to ride and the trainer made some noises then into the hardest drag, my ride started on the desert road so pretty flat, restarted the trainer, same happened so closed Zwift. Rebooted phone then started Zwift again, after about a minute it started to act normal again for the terrain, is there anything in the update that could have effected this. Im at level 37 and ride pretty regular and had this happen before using the phone.

Which trainer?
