The app crashes immediately when using Google Sign-In. The error displayed is: java.lang.NullPointerException: Attempt to invoke interface method ‘java.util.function.Function.apply(java.lang.Object)’ on a null object reference This appears to be a bug in the Google authentication implementation or OAuth configuration. I have already: Cleared app cache and data Updated Google Play Services Reinstalled the app The problem is still present on app version 3.0.579. Please fix this

not practical for me, i can do the real life ergonomic sitting with indirect technique, but fumble so hard trying this simulation. And I didnt try it once, i tried the simulation so many times, but it's a good sim tho, just not for me

Appreciate the huge efforts to make and develop such amazing app honestly, but it lacks an option for changing the setting for the left handed practitioners and also the downloaded videos is not working. Please fix these issues as soon as possible.
