A. To manage watchlists across devices, manually export your watchlist data from one device and import it to another. You can do this by taking screenshots or writing down the list and then manually adding them to the other device. For drawings, consider using a third-party app that allows you to save and share images or notes across devices.

B. Use cloud-based note-taking apps like Google Keep or Evernote to manually keep track of your watchlists and drawings. This way, you can access them from any device.
