I can’t replicate the issue locally which means this issue is circumstantial – the hardest to find and fix!
So, if the ACF WYSIWYG field saves the value with <p> tags around the url, then the url is not converted?
Can you try and find the cause of the issue?
Perhaps it is caused when saving in the HTML / Text view?
Had you used the HTML button to edit the HTML?
What if you delete the text, and paste in the url again on a new line?
Any other plugins running on the WYSIYWG such as tinymce advanced?
Any debug info will be great!
