We are experiencing some serious (5+ sec) lag in using the app. UI on One Plus 3 phones running android 6.0.1. From the pin entry through to switching between the app. screens. Clearing out the android app. data and cache can help for a short time but the issue gets worse as it’s used. Also the sign in with fingerprint setting can be randomly reset to off.
Also, I’ve been asked to accept the new T&C’s a number of times now. It usually re-appears when the UI is freezing/lagging badly. Clearing the app. from memory and reopening is the only way to get it to un-freeze.
