two problems we are noticing.
Firstly, its has "login" text twice when opening the app
Secondly some users report that when trying to sign in that it says "Unable to connect to server" but they can access the website normally. I am able to login to the app normally though.
All plugins are enabled for REST and authentication as well.
the app isnt published in the app store yet however you can download a copy from one of my servers: https://www.2solutions.co.za/sj5.6.trial.apk
