No longer able to add a SMARTY page link into replies! WHY NOT???

OK, so I am trying to point customers, posting on here, to the SMARTY contact page so that they can use the Chat to get help and yet I am getting this message when I post the link (spaces added to ALL references in this message to 'h t t p s' as without it keeps getting flagged 😠)....

'The message body contains h t t p s://, which is not permitted in this community. Please remove this content before sending your post.'


I have tried adding it as:-

h t t p s://smarty.co.uk/contact 

smarty.co.uk/contact

but nothing works!

I have added this link to MANY posts previously and yet I can no longer do this 😤!
Erm, WHY 🤔??
You can't even add the plain text of 'h t t p s://' 
I understand that links to 'other' pages are not allowed but to NOT allow links to their own pages 👎

HELP....... anyone?!?!?!
