Data Input Keyboard not Appearing

I don’t know if this is related to my last release of AppStudio or not, but I just started seeing it after installing Intermittently my keyboard doesn’t appear when entering data into a bootstrap 4 input control. It doesn’t seem to matter what inputmode (keyboard type) I choose. The keyboard itself doesn’t appear but the bar across the top of the keyboard with the up and down arrows and “Done” does appear. I’m running in the latest iOS as a web app. Unfortunately, I haven’t been able to recreate the error as it just seems to appear randomly, however, once it appears once it seems to keep appearing.

This isn’t something which AppStudio controls. It’s baked into HTML: if an INPUT tag has the focus, the keyboard should always pop up.
