I didn’t see any issues today (nor right now).

I just checked on my own browser. They load just fine. Did you recently add anything that might be blocking proton services? An extension or something like pihole? It's the only thing that comes to mind.

5 hours later and ProtonMail is still not working. And ONLY ProtonMail. Lumo now works, protonvpn.com also works, even proton.me worksd, except the thing I need which is Report a problem link which just does NOTHING. Ugh. Problem on my end can't be so selective that only Proton stuff isn't working somehow and even that not all of it.

i shared my telephone number via email to another protonmail user. a day later i get an automated spam call. so maybe* they got hacked. i was thinking this. but i dont think this anymore

In the UK and the Lumo app is working fine for me
