pwa has been working on latest updated xenforo as desired. it's possible that chrome did not detect the manifest file properly and created a regular shortcut. it happens sometimes. i suggest deleting the shortcut and trying to install the web app manually again.
Many thanks Chromaniac for your help, really appreciated.
I don't know if I have understand good. I have tried to uninstall the app from the device and delete all the shortcuts from the windows of the mobile, then I have tried to reinstall again the app, but nothing has changed. Was this what I had to do? Or you was meaning to do delete the app from XF acp and reinstall it again?
Exactly. Also to be noted that pressing on the 3 points up on the right, it open a little menu relative to pwa and not the menu as a normal browser, so it should be related to a pwa setting in some where maybe. But I haven't thouched nothing relative that in the last times, I have only upgraded XF to the last version.
We send different manifest contents based on the browser requesting. (As specifically, "standalone" only makes sense on Android, as we rely on the OS-level back button.)
You appear to have it set so your server is caching the results to webmanifest.php -- I can see a Litespeed related cache header in the response. This means that it won't react to the requesting browser as expected.
Greeat Mike, so quite sure is for that. For this is not related to the upgrade of XF. I thought this because I have added LS and update XF in the same day so I didn't think about that.
Ok perfect, I will check then.
Many thanks to you all for the useful help. Really appriciated.
