Observation links in daily updates email not fully loading

This has been occurring for a few weeks now, when I click a link to the observation mentioned in the [iNaturalist] New updates YYYY-MM-DD email, it results in an incompletely loaded page:

Links to users still completely load, as do links to things like “View all of your observations from…”

Sometimes the loading icon is a bit different:

The species information does load on the tab, however:

iPhone 7, running iOS 13.3

Can you forward one of these emails to help@inaturalist.org?

Is anyone else experiencing this?

tiwane - you can close this. It is apparently caused by my having installed and turned on Firefox Focus for Safari on my iPhone. Apologies for the bug report.
