I made a post about this on the Technical issue Forum but I figure this may be a bug with the new update and how it transfers data.
Ranked Play Server Connection | EA Forums - 12160454
Here is the post. It's not just happening in ranked either. It seems that all modes and even the firing range have some sort of connection issue since the new update. I had this on both Steam and EA Desktop post the initial installation issue fix. I don't know what's causing it, but it's only Apex I'm having an issue with. All the other games I play are working fine.
