What should I include?
Your platform, version/build, device/OS, whether the issue happens with one song or the full library, and any error text you see. The app Diagnostics screen is the best place to copy this info.
Does Retrowave use cloud sync?
No. Retrowave stays local/offline with no cloud library, no account system, no cloud backup, and no remote library upload.
Where do I get updates?
Use the Updates page with the same email address used at Stripe Checkout.
