I had run several times into issues with the Push changes button as I don't see if the all the photos collected were pushed to the cloud. Sometimes I have a couple of GBs of photos to be uploaded, so I could only guess until I check from the desktop or webpage if every photo was successfully pushed to the cloud. A bar with the upload progress will be really beneficial to make qField app better. Auto push changes feature is not useful if you work in some rural areas with weak signal.
