Mi desk lamp no pomodoro after update

After updating to the latest version the pomodoro function has been replaced by Focus mode and the light doesn’t breath anymore but goes up and down not in a smooth way anymore. Is this a glitch in the new update and how can I downgrade to the previous version please. The latest version I have is 1.3.9 0062
Before everything was working fine with a nice, smooth breathing. Now it jerks and it’s not as nice as before.

I am new here and not very good with these things and I’d appreciate your help.

By the way where do I find my account number?
