Re-trigger auto-upload

Is there a way to reinitiate auto-upload in the NC Android app?

I’ve set up auto-upload for my camera folder and it detected some new photos I took correctly. But I had some connection issues and the upload failed.
How do I re-trigger that upload?
Also, if I mistakenly stop upload of a file from the “Upload” page on Android app menu, is there a way to manually trigger auto-upload so it scans and uploads the new files in the directory?
