Apple Watch Mobile app dynamic attachments not displaying

Hi,
I’ve been using dynamic attachments for a long time time and they have worked both on my iPhone and Apple Watch.

Over the last few months they’ve stopped working on the watch (mine and my wife’s). I get the notification, but just a spinner where the image should be. Not errors being reported I can find.

We’re running latest iOS, WatchOS and Home assistant. Also running both the latest companion app, and also the latest beta. Still no joy.
I’ve removed my iPhone from integrations, and removed all trace of it and reinstalled. Still nothing.

I’ve also setup a test automation (below) which is based on the docs https://companion.home-assistant.io/docs/notifications/dynamic-content

Any thoughts?

Just an update to this one; I’ve categorised the post to the correct forum category :smile:

Secondly, I’ve just tried it using 2020.7 but still no joy.

Doesn’t anyone else have this issue?

Thx
