In order to permit ZwiftPower and CVR to access my Zwift Data, I believe that we are meant to go to this link to do so:
I believe THERE IS A BUG that if somebody tries to access that link from a device where they have SAVED their Zwift.com username/password that clicking the link results in Zwift getting caught in an endless loop. I had this problem on THREE devices (2 PCs and one Windows) that did NOT ask me to login to Zwift.com.
I had the same problem when alternatively trying to make these changes thru Zwift.com PROFILE. I know others have had these issues too!
Only when I went to a new device where I WAS asked to enter my username/password for Zwift.com was I able to OPT IN as I wanted to do so …
GDPR is tough enough on everyone without having to go thru this 20 hours of hassle, so if my diagnosis is correct, I hope that ZwiftHQ can fix this fast and we can all get back to racing with good results.
