Timer counting problem during training

[jacopo.grazioli.tecnico]

Good morning, while using the MyETraining app and Suito rollers I noticed that the countdown of the time of the various intervals skips a few seconds, for example it goes from 5 minutes and 20 seconds to 5 minutes and 18 seconds skipping 1 second and it does this several times every minute, I wanted to know if there is a way to solve the problem and if anyone has the same problem as me
