@Niveshkrishna I see this too, and the request goes to ./?/Appdata/... and there is a 302 found at times.

At other times, it loads normally and I see it go to /apps/snappymail/?/Appdata/...

I see this script is added into the header by boot.js, so any idea on what is happening here? Why is it not going to the right url always?

3. Open browser and directly access the app with the link : /apps/snappymail

Correct!
Most RainLoop links use ./?/ and then they become /apps/?/
I've modified them so they use /apps/snappymail/?/

Keep in mind that this is a Nextcloud issue where /apps/snappymail and /apps/snappymail/ are handled the same, while they should not.

@the-djmaze thank you for fixing the issue so quickly. Will test out the latest release and share feedback

[Niveshkrishna]

@the-djmaze The original issue seems to be solved, app loads fine without the trailing slash. But after updating app to latest release, Admin section is broken

[the-djmaze]

Admin section is broken

Yes, i know and already fixed for next release.

It is due to a change in layout as there were issues on mobile view mode.
And now that broke the Nextcloud integration layout.
