One of my questions was recently deleted. When I viewed it on the mobile site, I tried to click the “view 4 more comments” button on the answer, but it didn’t work. I tried reloading and the like, but it still won’t show.
Using Safari on iOS 12.2, on iPhone 7. Still happens in 12.4.
On desktop, I have a similar problem: there are a few comments (two or three) that I posted on the answer that don't show up when I click "show three more comments"; "this post has been deleted and its comments are no longer available" shows up.
Firefox 66.0.3, the latest release according to the about view; MacOS 10.13.2 High Sierra (most likely irrelevant). Still happens in Firefox 68.0.1, which is the latest update. The same exact thing happens in Chrome 75.0.3770.142, which is also the latest version.
