Common Questions
Purchase could not be verified
Make sure you are signed in with a valid Apple sandbox or App Store account for the build you are testing. If the issue continues, contact support with the product you tried to buy, the time of the purchase, and whether you are using TestFlight or the App Store version.
Rewarded ad credit did not appear
Keep the app open after the ad finishes and use Check Again if the reward is still verifying. Rewarded ad verification can take a moment if the network callback is delayed.
AI generation failed
Try again with a clear garden image, fewer labels, or a simpler layout. AI image generation can fail when an image is too large, unclear, unsupported, or temporarily blocked by service availability.
How do I clear local data?
Open the Poster tab in GardenPoster, then use Privacy & Support to clear local project data from your device. This removes local images, saved layouts, generated poster history, and prompt text stored by the app on that device.
