Cleaning up old tickets last night, I was cutting and pasting into both internal notes and reply postings from my normal MS Edge browser. Noticed we didn't have a version with the Merge and Link options so we upgraded couple hours ago. Now I can't cut and paste into OS Ticket if using the Edge Browser. C&P still work for Firefox browser. Is v1.14 still supporting Edge?
Does v1.14 support MS Edge browser?
1.14 has not bee released... so I would guess you are running rc1 or rc2. Neither are ready to be used in a production environment. I would recommend restoring from back up.
As far as your actual problem I've never had a problem copying and pasting from Edge, IE, Chrome, Opera, or Vivaldi.
