Hi,
I have a public webmap I need to share through a link/QR code but having tested it with my colleagues it behaves differently on different devices. On my phone (Samsung s9) it opens straight in the Explorer app which is great. On my colleagues phone (iphone 12) it will only take her to the "download ArcExplorer onto your phone" page despite the fact she already has it installed. On another older iphone it took us to the download ArcExplorer page and after 5secs a pop up appeared prompting us to open the app, which then took us to the map. On a Google Pixel phone it also worked fine, once the app had been installed. None of us are logged into an account on the app, to mimic the experience for a member of the public.
Any ideas why this would be? My link is https://explorer.arcgis.app?itemID=defb2c1d5f0746f9abb60b77c708c6dc
