For several weeks now, Google Maps no longer shows POIs in Garmin connect. So no restaurants or supermarkets on the route. I have searched everywhere in the settings, both in Garmin Connect and in Google Maps (on maps.google.com itself, where these are visible), but I cannot find a solution to the problem. Who can help me?
TL;DR try switching your map provider on the website or mobile app by clicking/tapping the “layers” icon, which looks like this: 
On the website, the HERE provider shows restaurants.
On iOS, either Apple Maps or Google Maps is available - both will show restaurants, but Apple Maps will show more POIs.
It does show things such as churches, parks, health care centres etc and still does, It did also use too show restaurants and supermarkets. Which now seems too be missing...
I see restaurants and supermarkets on the Connect mobile app, not the website (when Google Maps is selected as the map provider.) Both the app and website show certain other POIs like businesses, schools, places of worship, etc. (Ofc, certain POIs will only appear at a certain zoom level.)
There’s definitely no “sports-related POI filtering” happening here. (One could argue that a casual runner or cyclist would care a lot more about restaurants on their route as opposed to stadiums. I’ve run to a restaurant before, but never to a stadium.)
On the website, I can switch the map provider to HERE in order to see many more POIs, including restaurants. I can’t explain why the Connect website doesn’t show restaurants in the Google Maps view (unless this is a deliberate decision by Garmin), but at least that workaround exists. If you’re on iPhone, the mobile app gives you the option between Google Maps and Apple Maps. Although Google Maps in the Connect mobile app does give me a decent number of restaurants (and other) POIs, Apple Maps give me even more.
