No verification request sent to ceratin sessions

[famfo]

Describe the bug

When cross-signing a new session, no verification request is sent to my Element X sessions:

{
  "messages": {
    "@famfo:ccc.ac": {
      "BAmk73FfTU": {
        "from_device": "NBzxmuQvnj",
        "methods": [
          "m.sas.v1"
        ],
        "timestamp": 1770906963331,
        "transaction_id": "<id>"
      },
      "rWAucn1rwN": {
        "from_device": "NBzxmuQvnj",

        "timestamp": 1770906963331,
        "transaction_id": "<id>"
      }
    }
  }
}

All devices queried earlier:
