Trello Infelizmente ocorreu um erro inesperado.

[Sid Ramos]

Olá, estou recebendo este erro ao tentar mover um cartão via app/celular: 

"Trello Infelizmente ocorreu um erro inesperado. Pode ser que as alterações recentes não foram salvas". 

Não consegui encontrar nada sobre o assunto no fórum. Fica postado a pergunta. 

Obrigado,

Thanks @Soumyadeep Mandal for your help. 

I have just found the reason: 

For the same problem I have a different feedback in my mobile and in my desktop computer. While in my mobile phone I have the message "Infelizmente ocorreu um erro inesperado. Pode ser que as alterações recentes não foram salvas", in my desktop computer I had the following message: 

"Moving this card would put the destination board over the limit of 50 custom field dropdown options". 

In my case, I have different boards but I had to type the dropdown list manually in all boards. They were supposed to be the same, but as there was a mistyping in one list, then when trying to move the same list (50 to 50), Trello showed me that was not possible due to the 50 itens limit. What I did was to correct the mistyping and keep the 50 itens in both list. as they are exactly the same (50 itens in the dropdown list) in all boards, now I can move the cards fine from board to board. 

Thanks for the help,

Hi @Sid Ramos ,

Welcome to the community!

Basically, It happens because of the browser or app cache. So you just need to clear the cache and restart the app or browser and then it will work fine.
