No Zwift invitation...?

Hi,

I have no issues in receiving meet-up request from other Zwifters I follow. However, one Zwifter who I follow and he follows me can add me to a meet up but I never receive the notification via the companion app.

I have deleted the app, logged out and in, checked privacy settings and we both follow each other.

I even have a screen grab of me in their invitation list on the companion app :man_shrugging:t2:

Any suggestions??

Thanks
