Page Text Not Saving

I am trying to create a booking calendar page and everything has worked find except the main body of the text. I've tried adding it to the description box, and also tried using the page designer, but neither works. The description box text disappers when i save, and the page deigner says it has saved but then disappears when I refresh?

Sounds like the  server is rejecting it or a cache has been added to your hosting.

3) The name of the booking service.

Thanks Tim.

I suddenly had a thought that it may be because the text contained emojis (copied and pasted from an AI generator) and when I removed them it saved.
