On July 17, 2019 Endomondo made some unexpected changes to their service which prevents RunGap from uploading workouts directly to Endomondo.
This will take a few days to fix. In the mean time you can export workouts in FIT format and manually upload them to the Endomondo.com website.
Thank you for your patience.
UPDATE: Fixed on July 20th.
Update awaiting Apple's approval for the App Store.
Fixed in version 2.30 released July 20th.
After update Endomondo showing activity without maps preview on wall (auto sharing from RunGap and Apple Health):
In version 2.30 there was a delay before the map wa displayed in the Endomondo app. This has been fixed in version 2.31.
I still experience this delay with map update with current version of rungap/endomondo
