I am new to Glass development... so hopefully someone has experienced this issue or can tell me what I am doing wrong. I am basically just using the Mirror API sample app downloaded from Google/GitHub. Everything works fine.. I am able to deploy it to our App Engine account and can authenticate via the front end into the app etc etc....
When we make a change to the app and update it on our Google AppEngine instance, are all users who have authenticated lost? It appears that users need to re-authenticate after we make a changes to the code and update it.
I can't seem to figure this out. Please help. Thanks in advance.
