how is it a "nightmare scenario"? it's not ideal, but it doesn't sound bad (there are other browsers, workarounds, etc. it's not like these sites are forever gone because of a ransomware or SSL key exploit, etc)
I can't imagine "Old Navy" customer support is going to have much success telling iOS customers to install another browser (I'm not even sure that solves it).
Is old.reddit.com very unstable for everyone else in safari or just me? On my past 3 iphones through multiple iOS versions I can't browse for more than 10 minutes without eventually hanging/crashing safari. It seems to happen most frequently after browsing posts with images
To the point where it feels like they have pretty obviously intentionally gimped the mobile website to drive you to the app - which just makes me way less likely to install it. Page loads take absolutely forever, videos almost never work first try, their image galleries are essentially unusable... None of these are issues on desktop web (on the same network).
New reddit is just harmful to your laptop battery. It fulls one cpu core all the time if you don't block the update websocket. Truly the worst written react app I ever saw.
