Add to homescreen vs Install app

My pwa’s on my phone (Galaxy S9) have just started asking “Add to homescreen” rather than “Install app”. The icon naturally has a chrome logo in the top right of the icon. Desktop chrome still asks “Install app”

Is there a fix for this? Not an 8.5.5.0 issue? I’ve just upgraded.

This doesn’t sound like an AppStudio issue. Both Chrome and Apple have been tinkering with how PWAs work - it’s probably the result of that.
