Can't Manually add workouts or edit past workouts

Same issues with me. Spinning blue wheel

Yep - Ditto. anybody any ideas? Please!!! Btw - a workaround is to add on garmin connect android app - this uploads to online connect site.... Shouldn't really have too...

Manual upload works from the Activity pane in the Dashboard for me - not from the Activities window though!

Click the + icon at the top of the Activities pane.

Same issue here.

Edit button causes busy mouse icon and nothing else in IE and Chrome. Going directly to the edit url (i.e. connect.garmin.com/.../edit) brings a page with blank content. The following errors show up in Chrome's console:

• XMLHttpRequest cannot load https://sso.garmin.com/sso/login?service=http%3A%2F%2Fconnect.garmin.com%2F…erties%3Fbust%3D14.11.3.0&webhost=olaxpw-connect25.garmin.com&gateway=true. No 'Access-Control-Allow-Origin' header is present on the requested resource. Origin 'http://connect.garmin.com' is therefore not allowed access.

I can get around this by going back to classic and performing the edit there.

Same problem here - spinning blue wheel when I try to edit an activity.

The suggestion by m0hami01 works perfectly - switch to Classic Mode temporarily and then edit. Thanks for the tip!

Yup, same issue here. I can add an activity manually, but any attempt to edit and my mouse "hangs." This is true in Chrome, Safari, and Firefox. Fix it, please...!
