The form session key is missing or invalid

Have you ever had this problem? How do you solve it? (Android)

Possibly restart the app or login/logout.

This is an issue typically where the session key you have is outdated/cached and the server is expecting a different key. At least by the sounds of it. It's nothing you've done.

The restarting or logging out doesn't resolve it you might have to look at how to clear the cache. Even though it's an app, it's still basically just a web page so most of the time the same things apply.

I'll try it. Thanks for your reply

If anyone else is seeing this thread and hasn't solved the issue try changing the default browser on your phone from whatever it is to Google Chrome. That solved the missing or invalid form error for me.
