Version 1.6 fixes a severe performance problem that occurs once you have several hundred cards on a Board (including Archived cards). Depending on the speed of your computer and internet connection, Atlassian made a change that seems to conflict with one minor function of TrelloX.
For the moment I've disabled the function, so there will be a minor annoyance that TrelloX won't update formatting in certain situations. I'll come back and resolve this properly as soon as I can.
If you want to help with TrelloX and are experienced with JS/jQuery please contact me 😊. Time is my main barrier at the moment! 😭
