Low watts, low resistance

My zwift hub has started randomly only putting out low watts on group rides, races and group workouts, will not go over 100 watts and the resistance is super low and easy, everything up-to-date. ERG mode seems fine, i have no option in settings for virtual shifting, ive had the trainer for two months and it started randomly doing this last week. Super frustrating! Can anyone help??

Are you connecting over ANT+ or Bluetooth? You need to be on Bluetooth for virtual shifting to work.

Must be ANT+ then because when ive checked in the settings it doesnt show up, ive read on other posts this could be the problem, ive had it for 2 months and trained nearly everyday on it with no problems until this week.
