Ubuntu-image is preparing the snaps by using the snapd lib. From what I can see in the code, the env var UBUNTU_STORE_AUTH_DATA_FILENAME is still used in snapd, so this should still work.
We do not have test on this feature so I cannot confirm there is a bug without testing with a private store.
Are you sure the account you used is authorized to access the private store? Are you sure the macaroon in the store.auth file did not expire?
