If a previously existing message is automatically resent when joining a channel, only the preview is sent, not the entire message.
Using Desktop 2.59.0 on Ubuntu 24 and Arcane Chat 2.58.1 on Android 10 (tested both back and forth) for channel and subscriber profiles.
In detail: If a message is too long, “Show Full Message…” appears, see Figure 1.
Tapping on it opens the entire message, see Figure 2.
However, if the message has been resent, “Show Full Message…” is missing, see Image 3.
I even encountered a case where “Show Full Message…” was displayed, but the entire message still looked like the preview. However, I was unable to reproduce this specific case.
This test channel is currently still available via
