Keep seems to have gotten slower and slower over the years too - the web version is practically unusable on mobile, not just because the UI design isn't responsive (!), but because it's so painfully slow.
Boggles the mind how Google web apps have performance issues like this.
Wait, you think https://mail.google.com/mail/mu, the mobile web version aka "superpudu" is slow? Can you tell me your device? It paints itself in only 400ms on my iphone. I actually prefer it over the app because it's so fast.
My comments were about Google Keep, not Gmail, though I do actually find the Gmail web app pretty slow too - it takes several seconds to send an email.
I didn't know there was some kind of secret mobile Web version of Gmail - I get a blank white page when I open your link on mobile tho (using Brave)?
Oh, I totally scanned passed "Keep" in your comment. The mobile web version of that does indeed seem a bit rough. It's been a while since I worked at Google but when I did, Keep was a one-engineer project so the amazing thing is it exists at all.
