classified not posting

I frequently (about half the time, 3 out of six or 7 nights) can't place a classified because it hangs with the "Please Wait .." screen when submitting the ad.

If this happens, I try re-entering and posting several more times or even and hour later - still no joy. So happened tonight Nov 4 10:15-10:30pm PDT.
On some other nights it works just fine on the first try, less than a second from submit to the next page.

Windows 10, Edge browser.

I also swear I only pressed 'post" once - and now it shows this same post three times.

There are other forums here with ten to twenty repetitions of the same post, so this seems to be a recurring problem.

Same problem cannot post an ad.
