For me, ditto.pub has the best feature set of the browser clients and is the worst at loading events. Maybe my relays are bad or something idk. But one of the best features is "open in njump". That almost always solves the unknown event issue.
If you can get the note id you can drop it into njump.me and try a bunch of different clients. For example the note id of the parent to this note is note1mzgwpxmfcnaavk6kh9827y6npf93rm6x826l5q0f2a8ja2jtsdas02age9
Drop that after the slash for a super handy link. https://njump.me/note1mzgwpxmfcnaavk6kh9827y6npf93rm6x826l5q0f2a8ja2jtsdas02age9
