On some tablet devices, when the TextBox FocusLost event is fired, EnterPressed is always false. Below is a video depicting a user pressing the return key (lower right hand corner, a bit obstructed by watermark), yet the message isn’t sending on our TextBox. I did some debugging with this user and noticed enterPressed was never being set to true. This specific user has a “Cherry Mobile Magnum 10”, and others with different tablets reported the same issue. I was unable to reproduce this on an iPad, and any user I asked reported it being an android OS tablet.
Update: So far 2 users stated they were previously using GBoard, and when they switched to SwiftKey the issue was resolved. Other device was a Lenovo Tab4 8Plus
