Problems with Bing maps in Chrome and Edge but not Brave. PS Same with CUK!

[xoggoth]

Bing maps has not worked in Chrome for couple of days. Tried clearing cache and disabling extensions. Developer tools shows a long list of errors, ....not a constructor, ...cannot read properties of undefined etc. Exactly the same problem in Edge with the same list. Firefox shows an error MOZILLA_PKIX_ERROR_MITM_DETECTED.

What is really strange is that the only other site I have a problem with is CUK. Trying to log in on Chrome and it just sits there with logging in popup.

Both Bing and CUK work fine on Brave. What on earth have CUK and Bing maps got in common?

Nowt helpful on net. Any ideas? Cheers.
