As part of the transition from OrbitNote Classic to OrbitNote Modern, annotations that were made in OrbitNote Classic will not be carried over to OrbitNote Modern.
To avoid losing any important annotations on specific files, those PDFs will need to have their annotations "Burnt on" to the PDF so that they will be saved outside of OrbitNote Classic. This can be done using OrbitNote's Download with Annotations feature. This will need to be done through OrbitNote Classic prior to transitioning to OrbitNote Modern.
Note that while this will save existing annotations to the PDF, the annotations will no longer be able to be edited.
1. Open the PDF with existing annotations into OrbitNote Classic
2. Click the Download button in the bottom right:
3. Make sure the Include Annotations option is checked, then select Download:
This will download a new copy of the PDF with the annotations saved. When the transition to OrbitNote Modern is completed, the annotations will now be visible on the new PDF
Below is a quick YouTube video demonstrating these steps in action:
