I am a bit surprised this is still an issue even tho I just downloaded the app. slrpnk.net updated to Lemmy 0.19.2 a couple days ago and I’m experiencing the Bad Cookie issue caused by the switch. I fixed it with the browser version, can’t seem to fix it with any of the apps I’ve tried, including this one. The exact error message Im facing is “Can’t fetch user info”
Glad it’s working again for you!
