Trying to play Live Events Co-Op is a nightmare

Whenever me and my friend try to play live events together we got a disconnection. Every single time. We have tried everything on our side. Playing with both accounts as the one hosting the game, using only one tactic with our squads, deleting all custom tactics, updating squads in menus, everything you can find in these forums and NOTHING WORKS! We closed game, restarted console (PS5), rebooted internet connection... Nothing works

We only played (and win) the first match of the Toty Event 1, tried to play 32!!!!! Games and all got disconnected... Some at the 20 seconds mark, some at 1.04 exactly, some after a corner and even a couple in the second half... 

Played one game of Toty Event 2 and worked, after there were 8 games in a row with some kind of disconnection and it just sucks, we can't play together like this

We don't have ANY issue in Rivals... It works perfectly, the Live Events are broken for us... Even playing solo, 1/4 get a random disconnection

So, what can we do to try to enjoy the game together without these frustrations?

We had similar issues in fc25 but it got fixed (after several months of being broken)...
