Hi I have a problem with this notification poping sometimes:

What can I do step-by-step to get rid of that

Hello, this seems like an MSFS issue. Please submit a ticket with them.

what if I deleted the msfs navigraph in game panel and simbrief in game panel?? would this solve the problem???

You can test that, but I don’t think that this is the issue. I could be wrong.
