Don't ask him to add it, ask Apple, it's their fault. It's not a production feature.
And since it's Apple, you can't just use another browser as it's all the same crap on iOS.
You're stuck with something worse than the 2019 equivalent of IE6. iOS is a joke when it comes to web browsing.
Technical previews is for Safari on Mac OS, and that browser works quite well. It's safari on iOS that is a huge shitshow.
Its more unstable than ever before and far behind everyone else on features, and it's freakishly unconsistent. Heck, Apple can't make up their mind if they are having a click delay or not, so now they have it only for standalone.
Hopefully that class-action against Apple for the app store monopoly bears fruit (pun fully intended) so some alternative browsers can be installed on iOS (via Amazon app store or something similar to f-droid).
Note for those new to the party "Chrome" and "Firefox" on iOS are just skins on top of Safari, iOS rules require you to just use Safari if your app browses web. See 2.5.6 here if you don't believe me - https://developer.apple.com/app-store/review/guidelines/#sof...
There was some funky scrolling on this article I noticed on my phone which is not present on most websites/websites viewed through Safari backed mobile browsers.
