Me too…
This problem happened to me before a year ago and I contacted trakt support and they were aware of it and told me there gonna be a fix in a couple of days and they fixed it
But it is back again this year
Unfortunately, it’s still not working. Tested with Chrome Version 89.0.4389.114 (Official Build) (64-bit) [even with data reset https://trakt.tv/settings/data] and a clean Firefox 87.0 (64-bit). Any chance this get’s working again?
