Google Analytics not tracking AMP

Tracking was working until a week ago but now GA is showing no traffic from AMP pages.

I’ve confirmed AMP is still working, eg: https://www.tlcinteriors.com.au/inside-homes/chic-city-apartment-melbourne/amp

The tracking code is still installed:

{
    "vars": {
        "account": "UA-44809576-1"
    },
    "triggers": {
        "trackPageview": {
            "on": "visible",
            "request": "pageview"
        }
    }

I use Litespeed Cache and I noticed a thread about it adding comments to the HTML that caused issues, but I can’t see that it is doing that to my site.

The SEO plugin I use is SEO Framework and I have their AMP extension installed.
