Unable to comment or enter description to trello card

[Reimi Konda]

All of a sudden I can't comment or enter a description on the trello cards. I haven't changed the settings but now when I want to enter details or comment on a card, the entry doesn't get applied. I am the only one using the board in my workspace. I can still edit the cards on the trello app on my android phone, but I can't edit when working on my tablet app. What can I do to fix this problem?
