A. 1. Check for alternative apps: If Planimeter Pro is not receiving updates, consider looking for alternative apps that offer similar functionality and are actively maintained. 2. Provide feedback: While not contacting customer service, consider leaving a review on the App Store to inform other users about the lack of updates, which may encourage the developers to take action.

B. 3. Explore user forums: Engage with other users to find out if there are any unofficial updates or workarounds that have been discovered.
