Is Safari silently blocking some sites?

I'm using Safari Version 15.4 (17613.1.16.1.6) on Monterey 12.3 beta. I've been noticing that it hangs up (i.e. does nothing) on a number of sites. For example, this morning I tried to log on to pseg.com. After entering my userid and password and clicking on the link absolutely nothing happened -- no warning, no progress bar. When I went to firefox and did the same thing it brought up a Captcha. After filling that I could log on. I found that if I uncheck "Hide IP address from trackers", but check "Prevent cross site tracking" that I can log on In another case, I can't access linkedin.com. It just sits there. I found that I had to check "Prevent cross site tracking" and uncheck "Hide IP Address fro trackers" and then I could lo g on. At the very least it could give a warning message instead of silently doing nothing. This is rather maddening. Can't Safari come up with a consistent policy and warn the user when it's blocking something?
