Why do some buttons in the telegram bot not work on iphone?

Question

iPhone

There is a bot, they work in the main menu inline, everyone is pressed, if you go to the next menu (the message is edited using editMessageText), then the text and 6 inline buttons are displayed there, the first 2 buttons work, the rest of the buttons are not pressed, and in other menus, but it happens that the button is pressed, the message is updated, but then if you press the "Back" button, then the button that opened does not work anymore.
1. If you write any message to the bot, then the buttons begin to respond until the message is updated again.
2. Everything works on WINDOWS, ANDROID, the problem is only on iphone.
Maybe someone met with this problem?
