For a long time, Twitter embeds were displayed in the same way on web publications and newsletters. Unfortunately, in May, Twitter embeds stopped working (see this forum topic) for a few weeks, before working again as before… but here’s the thing: the embeds are once again displaying correctly on web publications, but are only showing text versions on newsletters. Are you experiencing the same bug?
