Signal user support channel is not reachable

We have received a report via email that our signal support channel is not reachable. I sent a couple of test tickets on Signal and am indeed not seeing them coming through on cdr.link.

Time stamps of test tickets: 31/03/2025 - 17:52 UTC, 17:57 UTC.

@acute, 👋, can you please check? Thanks!
