It’s probably a bit of both - wefwef has been around for literally just days at this point I believe, so I have high hopes it will continue to improve.
Beyond that, there are a lot of people who feel Apollo is/was the best user experience for Reddit, and there will be a LOT of devs trying to emulate that - one way or another, we’re going to get a high-quality Apollo replacement eventually.
Yeah I can also see that animations aren’t as smooth as Mlem or other native apps, but it’s not bad enough that it bothers me. On an 14 Pro also.
I imagine this has to do with the fact that PWAs likely don’t have access to full hardware acceleration for graphics, but I also don’t know enough about PWAs and iOS to know for sure.
