Uninstall the app from the Watch, reboot (power down-up) the Watch, reinstall the app.
Then…
- Launch Drafts on the phone and leave it (hit home button).
- Launch Watch app - do your inbox drafts load up?
- Try to capture again.
Updates should be pretty immediate. I think you may have gotten something stuck in the transport queue between watch-phone. Haven’t seen it come up too often, but now and then and only a reboot of the Watch (and occasionally the phone) seems to fix.
There was an issue with some captures not transferring, but I’m reasonably confident that is fixed in the 5.2 release.
