GeoJSON features: adding points seems cooked in Mobile\Mapbox component?

Brains trust! Back again Sooo, I connected a Supabase PostgreSQL instance with PostGIS extension installed so I can play around with geom values. I’ve been able to create a SQL query to generate a constructed geojson object to plug directly into the mapbox geojson field.. running the query and constructing the geojson wasn’t an issue however it wasn’t loading into my mapbox - when I hardcoded a couple of entries, directly into the field, I noticed the same issue! So I’m wondering what have I done wrong? See below the current value I have hardcoded into the geojson field with no success:

{
  "type": "FeatureCollection",
  "features": [
    {
      "type": "Feature",
      "geometry": {
        "type": "Point",
        "coordinates": [152.63168, -27.36744]
      },
      "properties": {
        "id": "487ce414-b287-4189-8ec6-1e566d844ba8",
        "notes": "Native colors"
      }
    },
    {
      "type": "Feature",
      "geometry": {
        "type": "Point",
        "coordinates": [152.89, -26.536707]
      },
      "properties": {
        "id": "110e0708-ed89-44ae-b609-d5c0e3deab1a",
        "notes": "Dark Morph - location estimate"
      }
    }
  ]
}
