Protect your information. Never send a real identity document, signature, seal, or unredacted file when reporting a problem. Use a generated sample.
A purchase is not recognized
Open Upgrade, choose Restore purchases, and confirm the device is signed in to the Apple or Google account used for the purchase. New store products can take time to appear in testing.
An export looks wrong
Reopen the exported file in a separate viewer and inspect every page, especially rotations, redacted areas, and signatures. Keep the original file until verification is complete.

A monitored support email will be added before public store release. TestFlight and Play testers should use the feedback channel included with their invitation.
