My name is Andreea Enciu and I am using repl. it HTML/CSS/Java editor for websites on my Android tablet with a virtual keyboard and I've encountered some issues. I've tried a different browser and different virtual keyboards but the issues were the same. First off, the Android pop-up menu copy/paste functions do not work, and most annoyingly, every time I use Space or Shift, the last character gets deleted. I haven' t tried a physical keyboard to see if this persists, but I am hoping it is not the case. The keyboards I've used are Gboard, BeHe Keyboard and Swiftkey, and the browsers were Chrome and Opera Touch. Hope this was useful.
