Since I installed on my iPhone 15 pro IOS 18 beta 5 I have the following problem: When I shutdown my phone, for all “ Find My” friends I have underneath their names “location not found”. The same bug happens with my iPad 10 same version and with my wife’s iPhone 15 same version. The work around I found was going to my address book under my wife’s name stop sharing my location and then reshare my location back with her and then location not found for all my friends disappeared. The solution was provided by an Apple agent but the thing I didn’t know at the time was if you shutdown your iPhone again all this process as to be reimplemented again. That is a bug for IOS 18 beta 5
