I noticed the game doesn’t give me buddy credit for the snapshot if I take it immediately after I get the hearts for playing with the buddy. If I wait a couple of seconds after that, I get the credit, but the lights and hearts have already dissipated. (Getting a snapshot of the hearts doesn’t give the credit.)
Yours don’t show the hearts, so apparently that’s not why it’s not giving you credit. No ideas here why that could be.

8/24 update: This issue has been updated to indicate that it does not only affect buddy snapshots Issue status: Resolved in update currently rolling out (0.185.3)
