Hi, I just signed up for an account today, but I hope my feedback can still be deemed valid. I'd like to preface this post by saying that I'm accessing the site on mobile.
I was trying out the Beauty Counter earlier, and there are times when the page freezes. Not the entire page though, I can click the hamburger icon and the menu opens. When I was finally able to scroll, the customizations options move on their own. Nor sure what was going on there, but that hasn't happened on any page I've visited before, so I think I can rule out it being my phone screen's fault.
The same freezing issue occurs on the Pet page. I have to click the hamburger icon to unfreeze it. (I also noticed there's some noticeable lag in updating the lists. This includes the inventory. Not sure if that's a caching issue or your saving and fetching from the server takes too long.)
Finally, dark mode. I set it to always on, then accessed my inventory. I noticed that some items have transparent backgrounds so they disappear into the darkness. (Like the mushroom seeds.) A bit later, the site turned off dark mode on its own.
I'm looking forward to how this site will improve in the future. :)
