@Vladislav Pestrov welcome to the community! is this trello.com in mobile browser? or in the app? I know the app has had a couple issues in the last week and Trello just released a new update, so maybe try to do that if it's the app! If it's in the browser, I'd still recommend trying the app - works much better than accessing trello.com on safari/chrome in mobile!
