content: The app works mostly pretty well but using Bluetooth is wildely inconsistent. Sometimes it will show that youll be connected with Bluetooth and then once you join it wont use it. When it works corectly you can use BT your phone or speaker but whe it doesnt you have to hold it up to your ear. This is obviously a problem when im traveling and someone is presenting or im in the car. Well documented problem for a couple years on the internet that MS should have fixed by now.
