I was also enjoying the "Sorry, something went wrong. Please check your network connection and try again." I had that particular pleasure about a year and a half ago and fixed it back then and tonight with the following instruction,
I followed the instruction in the following, "To turn on the "New Experience" go to the megaphone icon in the title bar (on the right side) and click on it. This opens the Coming Soon pane. Scroll down in that until you find a switch to turn it on. Then restart Word.
Note, if you turn on the display of text under the New Experience and switch that off, the text will go away."
In my case both times, I was attempting to change the icons on the Quick Access Toolbar to Text, which following the advice in the above quote, and the "Sorry, something went wrong. Please check your network connection and try again" did a fantastic display of disappearing and the Text showed up instead of icons. Totally refreshing!
