No, the privacy level will not 'autochange'. It will stay the same as it is. That is why only a Profile Manager or someone on the Trusted List can approve it. It will stay the same even after the 30-day default, so once again you have to be a Profile Manager of that profile or on the Trusted List. It is very annoying when one of the PMs left WikiTree months or even years ago. Then you have to go through the "Unresponsive Profile Manager" process.
