EA App invite by computer or by account?

I opened Origin on my MacBook Pro and was given the link/invite to finally move to the EA app (expecting more reliability). I installed all of my expansions and packs/kits/etc. It wouldn't open.  So I did what I always do and launched from the Sims app icon (plumbob) in Launchpad after closing the launching app (no longer Origin, now EA). I did not have time to play, but it DID open. Closed it all out.  This device is at work now, and I am at home.  I expected the same from my NEWER desktop Mac when I got home.  NOPE. I have restarted, logged out, refreshed, updated, repaired.. no invite from Origin.. I can launch my game.. Oh.. and EVERY SINGLE LOT IS EMPTY. there are caution triangle with an '!' symbol above every single lot in every world, and I cannot even SEE the destination worlds.. basically says no vacation lots available... I was in "travel," and after an hour of trying to troubleshoot, I was done. It may show up in "vacation," but maybe not..?

So, are you still PILOTING the EA app....? Because I NEVER would have downloaded it on a computer I hardly ever play on had I known.. and now my entire game is nonfunctional, and everything I built is gone... not. okay.  I DO have mods installed, but I was promised that nothing would change.  Actually, every single damn mod is still functional and intact, no issues. Mac/Origin never even almost launches sims 4 if mods are corrupt/out of place, in my experience.. I can't get any answers on forums because most people are just saying their EA app isn't working.. well.. mine launches.. but when I launch in origin on my primary PC, it is basically empty outside of the sims themselves.  All lots are blank.
