Primal Android app reads the relays from the content field of the contacts nostr event. I have just checked and both your and nostr:npub1prya33fnqerq0fljwjtp77ehtu7jlsjt5ydhwveuwmqdsdm6k8esk42xcv's contacts list have empty "content" fields. Because of that the app doesn't know where to post the notes and shows the error.
Can you check if you have published your relays list on other client?
I have and most other clients list the relay list correctly but indeed on Primal web it shows an empty relay list.
Though on https://nosta.me/npub1rqlwyvfshkj2778cc0lv46geppfhgxc73uqfcc0zpz3gy5d07uasj6c9tx you can see it displays the list properly.
On https://metadata-contacts-relays.pages.dev/ as well.
Actually Primal web also shows the relays, it's probably an app issue then.
