Looks like your site is broken when viewed on an iOS mobile with Firefox Focus (anti-tracking) is enabled. Not sure why disabling the trackers should break your site...
My hypothesis at the time was that Google had deliberately introduced changes to GA that made it far too convenient for sites to depend on on ga.js for providing [something in the path of] actual page rendering logic. And so for a number of years any URL pointing to blogspot was as good as dead to me.
The asinine behaviour has since been fixed. I can only assume the pageview numbers with intentionally parasitic ga.js were going down and couldn't be misattributed any longer.
