I can't open an activity in GC. The calendar doesn't show. I cannot click on the three lines in the left corner. This has been going on for a couple of weeks and I've tried both IE and Safari. Prior to this everything worked great. Haven't changed any settings.
There's not a general issue here so something has probably changed your end. Have you recently installed/updated any firewall, AV or ad blocker program?
Thank you for the reply. No, I haven't installed or changed anything. I even tried to log in at work (as in "not my computer") but had the same issues there.
Since you have tried at work also then it seems unlikely that it is something local on those PCs - you should contact Garmin support so that they can check out your connect account.
