I've been driving a non-Tesla EV for several years now in the US, and have gone on many road trips. I sometimes make a point to try out new DC fast chargers around me, even if I don't really need the charge, just to see what their experience is like with a lot of the newer networks.
I haven't had to use an app to deal with payment for a fast charger in years. Practically all the major networks these days have ways to pay at the dispenser with a credit card.
The last time I used an app to charge was with some chargers at my office which were free for a few hours for tenants in the building, the app was needed to add my car to my approved account and once added it auto-detected and the app wasn't needed.
My car doesn't exactly go to Europe very often, its a pretty challenging drive. So I don't get why Europe having a different plug really makes that big of a difference in the end. Would it be nice if we could just have one world plug? Sure, but not too many cars from North America are going to accidentally find themselves in Europe without much planning.
As for charging protocols and plugs in the US, I've never really had too much of an issue. For a while it was pretty much just choose a non-Tesla charger and it'll be compatible. These days in this mixed period, lots of chargers support NACS and CCS, even Tesla. I got a free adapter from Ford but outside of using it once to test it out I've never used it.
That's encouraging, about the payment.
My information is 6 months old: I borrowed an EV to travel around while visiting friends in the US. I've never had any issues paying with a credit card at a gas pump, but had an O(0.1) success rate with the EV charger. But I guess wherever you are the payment is sorted out better.
The mysterious thing to me was why they ever tried to reinvent this part of the procedure. As I said, it was one of the few things they could just copy from the working model.

You definitely have enough info to figure this out, but let me walk you through it.
What is the profit margin on the business of transporting or distributing commodity energy like electricity or a tanker full of gas? Not very good. It's a commodity, so you can't do much to improve your margins without someone else undercutting you.
Modern Businesses in America do not like the small profit margin of selling commodities. They like the "tech" standard of insisting that an app is a "Platform" or community and being able to extract whatever rent you want from it.
So they tried to control a "Platform" through the cars. It somewhat failed because it's finally a bridge too far for consumers, just barely.
Basically, a classic horror story of consumer rights is "What if your ford car only worked with ford gas?" which was not something possible to really do back in the early 1900s, but companies saw an opportunity to do exactly that with EVs, and they don't care that it made things worse and slower to roll out and harmed adoption, because there was a chance of infinite money!
The working model has less data tracking
