The new update in trello (2.13.1-438) has some serious bugs. You cannot move,open, edit cards. The list does not load properly for minutes. The software freezes and does not respond to any action. The problem continues even after restart. I can only use trello on my android but not on my mac.
By the way the other issue is that the previous version was forcing the cpu increadibly. The fan runs like an electric heater. When I check the activity monitor it is seems like reason is the trello renderer. Even it works on background and I was doing nothing with it.
