My experience with Zwift so far is a disaster and I’m going to look into alternatives. Clearly you do not respect your followers. I put in a ticket because of the problems I had signing up. To accomplish this I ended up creating two account. One needs to be cancelled but there is no such option in my account so I will just put in a fake cc number.
Saving to Garmin only works about 1 out of 3 sessions. And if it doesn’t save to Garmin, the fit file I would use to upload to Garmin is corrupted. Do you or do you not support saving to Garmin?
I need a faster response than 2 weeks! Like later today would be appropriate
Try disconnecting your Garmin and account and reconnecting it. Uploads to Strava have been an issue for some, I would guess this is due to the increase in membership and the increase in activities being synced.
Are you using a PC, Mac, iOS, or AppleTV for Zwift?
Where are you getting the .fit file from that it is corrupt?
