After renewing my subscription, why are my older reports missing or not syncing, and how do I recove
If you were using the offline version, the reports are only stored on the device that created them and won't be automatically copied to your new device. You will need to back up and restore the old data from your old device to the new one.
If you were using the cloud version,
make sure the older reports are uploaded to the cloud by opening the app on the older device and allowing it to upload
make sure you are logging into your new device with the same email address as your old device
