Media upload pending despite switching off "WiFi-upload only"

If in settings "Upload photos over Wi-Fi only" is checked and data have been collected, unchecking it does not trigger the upload over mobile data.

This is a big problem at the moment for a geolocation campaign in Nigeria, where several data collectors had "Upload photos over Wi-Fi only" checked. After unchecking it, the photos keep pending in *Data sync status* and are never uploaded. (Once connecting to a WiFi, the photos are uploaded immediately. The Nigerian campaign is trying a workaround, connecting to hotspots, but this needs urgent fixing, therefore P0.)

Tried on older version, this seems to be an old undetected bug.

Andreia is on leave. Are you @shobhitagarwal1612 or somebody else available to fix this?
