A glitch in Mi Band 3 after the update writes Open the application. What should I do? Is it possible to solve the problem on my own?

Question

Operating Systems

After updating Mi Fit, which in turn also updated Mi Band 3, as I understand it, it knocks out on the gadget’s screen. Open the application, the Mi Fit program shows that the bracelet works, but I can’t do anything on the gadget itself .... Help with advice on what to do ..... The bracelet is connected to a mobile device with an IOS operating system ....
PS /. Rebooting the phone didn't help.
