This morning, I have been having troubles uploading my AppStudio app for testing on mobile devices with AppStudio Player. I have been getting timout errors (code 504), messages that I am unable to update my item info. I tried uploadinf another app and the same is happening. I'm guessing this is due to server issues, so is there an expected time for these issues to be resolved?
I can not reproduce this issue. I can update and upload the apps to ArcGIS Online today.
Are you updating your apps to ArcGIS Online or ArcGIS Enterprise?
