Chat services at&t galaxy s22 don't work.
When sending a video or picture I see the request go out for " ftcontentserver.rcs.mnc410.mcc310.pub.3gppnetwork.org " but my content never sends. If I disable "private dns" the message content sends. Only occurs on mobile network with private dns enabled (wifi enabled works). I'm concerned "ftcontentserver.rcs.mnc410.mcc310.pub.3gppnetwork.org"is not in NextDNS name records.
Checked the setting is off I've never used it. I've added the ftcontentserver.rcs.mnc410.mcc310.pub.3gppnetwork.org to the allow list with no luck. I even tried DNS rewrite to point to the IP reported by Google DNS, with no luck.
