Installed PWA - blank screen on launch
I have a web PWA at https://ourcardgame.ca After opening it in Edge, the option (icon with plus symbol) to install the App appears in the address bar. Clicking that and choosing "Install" works ...
It turns out that the problem was in the PWA's manifest.json file as described here: https://stackoverflow.com/questions/54928050/vue-pwa-blank-screen-after-closing-the-app
By default, the manifest file had "./index.html" as the start URL.
{ "start_url": "./index.html" }Changing that to be "/" resolved the problem.
I saw what you have said and I am also seeing the same. I would recommend you send feedback through the in-app feedback tool(Alt+Shift+I) in Microsoft Edge with the diagnostics data attached which will help the PWA team to look after and resolve your issue.
TheShaunSaw Thanks for the suggestion. I've done that now.
