Is normal getting 404 in a recently published app?

A few hours have passed since I published and https://flathub.org/apps/me.sergiotarxz.JapaChar continues being a 404, other apps that got merged today do not have this problem.

It is still happening.

Yeah, caching might be a bit aggressive there.

If you try other languages it works Japachar auf Linux installieren | Flathub

It is working now, I am so glad it is not an issue because of my manifest or something like that.

I hopefully finally figured out how this happens, and it should be much more common now.

Much less I hope, I think you had a typo.
