I have been using Trello for 13 years - I Iove it. But today I am making changes to my board that are not "sticking." For example, I moved a card from one list to another and it moved back. I have done it 3 times so far today. I have not seen this before but I can't use this app if it won't save my changes. In fact I just checked my board and the card had moved back again.
