When you put URL place holders into URLs it does not generate appropriately.
*It use to work OK - something has changed.
Step 1. Insert Hyperlink
Step 2. Go back and edit the hyperlink you can see that it has added ad additional "http://" Which is wrong because the Ticket URL contains this already + It is HTTPS.
I guess you could edit the HTML but we shouldn't have to do this.
Thanks for bringing this to our attention.
We were able to recreate the issue in our staging environment. Let me pass this to our Product team and will keep you posted on the status.
