Autoupload on android is very delayed

Nextcloud version (eg, 18.0.2): 3.14.1
Operating system and version (eg, Ubuntu 20.04): Android v10

The issue you are facing: I installed Nextcloud app and set up autoupload on the folder where phone camera stores pics. The existing pics were uploaded fine. New pics are uploaded, but this occurs hours after the pics are taken. What might be causing the delay?

I was previously using Dropbox to autoupload pics from phone, but turned off the “Camera uploads” option in Dropbox after setting up autoupload of camera pics in Nextcloud app. Not sure if there is some residual effect from having Dropbox performing this function?

Steps to replicate it:

  1. Take pic
  2. Wait several minutes, then check nextcloud server for pic - it’s not there
  3. Wait several hours. Pic is there.
