IOS 11.3 Webapp issue

[pehebo]

Hi,
Before IOS 11.3, when you sent the link to your volumio from safari to your homescreen, the next time you open that link, volumio started as a webapp, meaning in fullscreen with no browser navigation bars. Since 11.3, this doesnt work any more, mostly, because apple changed many things concerning webapps. Any idea how to fix it? I found that meta name="apple-mobile-web-app-capable" is ingnored or doesnt work anymore.
Thank you very much, and best regards,
Peter

i found that if you add this to the beginning of the manifest.json, located at: /volumio/http/www/app/themes/volumio/assets/variants/volumio/
"display": "standalone",
and after that send the link to homescreen again, it works!
This is because in IOS 11.3 Apple changed a lot in the behavior of webapps etc.
Best regards, Peter
