I had a phone call to Apple support. They helped me to enable the feature again:
1. Tap Settings > [your name] > iCloud
2. Turn off Safari and choose Delete from My device
3.Wait few minutes
4. Turn off/on device
5. Go back to settings and turn on Safari
In about 1 minute I can see pages from other devices.
Are the other devices also running iOS 13 or Mac OS 10.15?
If not that’s why.
Something I really try to avoid to not loose my extensions.I think you need to update Safari on your Mac. I've Safari 13.0.1 and it works.
