Howdy there!
There is a known bug that affects UMG widgets from receiving emulated enter and backspace keyboard key presses in 4.15 (the bug report says it only affects the Backspace key though). This bug has been labeled as ‘Backlogged’ so I was not/am not expecting it to be fixed in 4.16, however this same bug does appear in 4.16. I’m just making sure that the report can get updated to reflect that the bug affects 4.15 AND now 4.16.
