Google calendar event issue

Hi everyone,
I am creating an automation to create an event in the Google calendar. After the event is created, it appears in the computer version but in the mobile version on Android it does not appear at all.
Only after I make an update in an event directly in the Google calendar, then the same event is updated and appears in the mobile version as well.
What could be causing this and how do I fix it?

can you share how you have set things up so that we can potentially help?
