Timer not work in subtask of mc60

Hello
When I set the timer, it is registered in the main function of mc60 and it works, that is, when it overflows, it interrupts, but when I do the same thing in the subtask, it registers, but does not interrupt and dont call the timer callback. Can anyone help me?
Thankful

Hi
First you need to print the log to see if the timer in the subtask is registered properly, in addition you can add a print in the subtask to see if it is triggered, can not be judged by the module behavior, because you are not sure if your behavior is working properly.
