I did submit a ticket and then a little later it worked.
Got an email back from Strava quite quickly.
On November 12th we experienced system backups beginning around 3am Pacific Standard Time. These backups caused the following issues:
• Upload/syncing failures and delays: This includes mobile app, manual uploads, and 3rd party uploads.
• Delays in editing activities: This includes changing sport type, cropping, renaming, etc.
• Failure to view activities: Clicking into an activity fails with our 500 page— “Oops! There seems to be a problem”
• Delays or failures to delete activities: If you delete an activity, it still appears in the feed and may prevent you from uploading a replacement activity.
• Seeing duplicate feed entries
• Among other issues
If you are experiencing any of the issues above, please wait 24 hours and then reach back out if you’re still having trouble.
Thanks for your patience as we work to resolve the issue!
