This has been going on on PS-EU for a while now. Since the previous update (so not this week's update). But I personally experienced it for the first time yesterday and two days ago. But members of my guild have experienced it even in the week before.
Here's some insight from a long time ESO player who has played for years both on console and Xcloud streaming. Every new major content update brings new bugs. Also, this Gold Road update is enormously popular ( especially with the spell customization feature ) , so tons of people will be logging on . I'm talking players that hate the game and abandoned it since Summerset. I've even ran into players that have just NOW returned after giving up YEAR ONE. so Gold Road is going to be a MASSIVE tsunami of bugs and server lag. You have players coming back that havent playerd in 9 to almost 10 friggin years. They finally saw the huge content changes including the spell customization and are logging in like crazy.

Oddly enough, people are in fact coming back to this crazy game and they want to see how all this works out.
So brace yourself for some crazy lag. Don't even think about going to Cyrodil LOL, it will be a friggin dumpster fire.
But it's also fun to log in anyways and see how it all melts down.
Lastly...the devs at ZOS and the 3rd party temp workers they hire....probably have experience by now with all the insanity of the "mega server", so I actually am hopefully they will fix things in a timely manor. After all, u gotta have smooth game experience for all those new and returning players . Can't have them unable to access the Crown Store 😉🤣
