Here are some tips that may help if you're having trouble logging into the mobile app:
- It's easy to make a typo on a mobile keyboard. Triple-check that you entered everything correctly.
- Where to find your subdomain / account identifier if you don't remember it.
- Username and password are case sensitive. If your username is "Fred", you will not be able to login by typing "fred".
- Your username is not usually the same as your email address.
As a last resort, if none of those steps helps, you can always try uninstalling the Kickserv app from your mobile device, reinstalling it, and then try logging in again. You won't lose any data by reinstalling.
