Mobile App Bug: add account button

Recently i notice the add account button on steepshot app is not working properly, when I was trying to add another account on steepshot using the app, it keep bring username doesn't exist, I was surprised because I just log the account out

below is the account I was trying to add. it login first, as you can see in the video below.

Since the app can allow two more account on steepshot, so I decided to test it by adding another account to it but I was surprised what the result showed. Video below

Without this bug been fix, adding of two or more account wont be possible.
