Well, this is new. I purchased Symfonium from Google Play Store sometime ago, and downloaded it to my sony xperia1. How can I restore purchase information into a de-googled sony NW-ZX505? The player is mine of course.
PS：didn’t know the order screenshot would go public, so I deleted it, can E-mail you if needed.
This is covered in the FAQ, this is not possible.
License purchased on Google Play are managed by Google and require Google Play. You can usually side load Google Play on that device.
There is a solution for degoogled device How can I pay for symfonium without google play? - #2 by Tolriq but no migration as it’s very manual and actually cost me money in the long run to offer this.
OK, THX. I’ll give it a try.
