I am the developer of the Progressive Web App (PWA) FindMeSAR which displays the user’s coordinates in several different formats. https://findmesar.com
When this PWA is not installed on my iPhone 17 Pro then I can use Safari to open this webpage and give permission for it to use my location. FindMeSAR works fine and displays my coordinates as latitude longitude in decimal degrees.
I can also use Safari to open Google maps and geolocation there also works fine.
But if I install FindMeSAR for use offline as a PWA then I get an error message saying location is denied.
My iPhone has the latest iOS 26.0.1
I should add that I recently traded in an iPhone 13 Pro with iOS 17. FindMeSAR worked fine on that device as a PWA including the geolocation feature.
Has anyone else with iOS 26 tried a PWA that does geolocation? Results?
