I'm definitely not an expert on this. However, I've found in the past when I've upgraded/updated a program that I hadn't in a long time for whatever reason and/or turned on auto updates, for a short time thereafter I would be getting frequent updates. My assumption has always been that there's a sequence of events that needs to happen. Meaning that you're in catchup mode for a while.
You piqued my curiosity with this. My old inexpensive acer convertible windows tablet upgraded to 11 and my newer powerful desktop didn't. Which option did you use? I checked and I could do option 1 if I decide to give it a shot. Did you have to reload all your apps?
