no imagery here message on maps in Safari

I am repeating this question from another user as there has been no response so far and this is a real problem for me. I am using Safari 15.6.1 within Catalina 10.15.7 and am experiencing this issue when a map should appear on certain websites. What I see is a plain page with just small icons where locations should be and the message "Sorry we have no imagery here" These all worked fine before. I don't think there are Apple software updates available. I have tried some of the cache and history deleting suggestions found on various forums with no success. I have however found this problem does not occur on my much newer IPad mini or IPhone. Any suggestions welcome, should I simply use a different browser?
