We were aware of an issue where loading the app on an iOS device caused the app to crash, and wouldn't load. We released a patch to resolve this issue (11.02.20). Check your app is up to date on the Appstore to get the fix. 

Deleting and reinstalling the app will allow you to use the app without downloading the app update. 

This was caused by a combination of our latest firmware release and an iOS update from Apple.
