MFi controller no longer works – Virtua Tennis Challenge Review

Update 6/19/19: Steelseries Nimbus MFi controller analog sticks no longer work with this game. Directional pad does work, however I miss the analog stick control. Same situation with Steelseries Stratus. Running on iPad Pro 10.5, iOS 12.3.1. Both of those controller's analog sticks used to work correctly in iOS 11, please update for iOS 12.X+
