Rlig feature not applied

In Simon Cozens' Introduction to OpenType features:
"... there is another feature (rlig) for required ligatures, those which should always be applied even if the user doesn’t want explicit ligatures."
In a recent post ("OpenType features documentation"), John Huston and Nick Shinn answered my question by recommending the use of rlig to force the use of the feature.
As it's absolutely required by my font, I followed their advice and it worked well with most of my applications.

Having published a new font (.ttf) on daFont and 1001fonts, I remarked that the rlig was not applied in their example text. The manager of 1001Fonts examined their text preview rendering system and asked me to provide an .otf version of the font as a temporary workaround, which proved successful in that matter.

Does anyone have an explanation of this problem? Or specific recommendations?

Thanks in advance!

    So the CFF .otf works but the .ttf does not?

    That’s very strange, because OpenType Layout should be independent of OpenType flavour. If the same .ttf works in other environments, that suggests something unusual in 1001Fonts’ text preview system. Can’t offer more comment than that without knowing how that system works.

    Exactly, John, that's what the manager told me: he's searching for a solution. When he finds it, I'll let you know
