I wanted to test out how does my app handles update so I checked checkbox 'Update Mode' in Run Configuration window.
Then while uploading I got
Unknown Error [90]
I tried restarting watch thinking there could be some background service running in my app (which I have) but I still get the same error. Disabling Update Mode worked - but the app has been removed and with this all of data stored in database.
Do you know what could be the reason? I tried it a while ago and it used to work. Couldn't find any useful information about code either. Any help will be appreciated.
