Devices not adding events automatically

Hi everyone,

For some time now events such as flights and concerts (that I believe have been added through my Gmail) are not being added to my calendar automatically. I have checked and both calendar and Gmail app have the Siri and Search enabled, just like Google suggests. The last time it has worked is about July 2025, I'm not sure if it is connected to some update or not. Any help is appreciated. Thank you!
