[Mi 9 SE] Data desactivated time to time

[Nokolo]

Hello, little worries with my Mi 9 se on global EEA 10.2.9.0. So, from time to time, my Data is deactivated and can not be reactivated (the button in the drop-down menu is grayed out) I have to restart my phone each time.

What I've done witout success :
-Set to never the timer to desactivate the Data when phone is locked
-Enable the settings in the dev option to always enable the Data

What I'm currently doing:
-Switch from Sim Card Slot 1 to 2.

Any idea ?

Thank you. ​
