I normally edit on a Surface using wireless keyboard and mouse connected via USB port. Initially found I could not edit text blocks in Chrome so switched to Explorer. Assumed it was a browser issue as had no problem editing in Explorer. My Surface just upgraded Explorer to Edge and had the same problem - couldn't edit any text blocks (shows a blue line around the block but no text editing toolbar). Tried all the recommended solutions e.g. clearing browser, checking cookies, javascript etc. No joy and extremely frustrating. Having read Reiko's post I just tried going back to a wired mouse and the Surface's original keyboard. This seems to have fixed the editing problem (fingers crossed) so appears to be a mouse-Surface connection issue.
