I recently had that when some people wrote a message in a Telegram group that I participate in with mautrix-telegram, instead of seeing the message I just see

his message is not supported on your version of Mautrix-Telegram. Please check https://github.com/mautrix/telegram or ask your bridge administrator about possible updates.

The message source of one of those messages as seen by my Matrix client is (I have censored some potential sensitive information):

    "body": "> <@[censored]:[censored]> > *Insofern wäre ich besonders an Erfahrungen interessiert, die weitere Wege beschreiben, mit Dingen umzugehen, die ihm\\* nicht passen. Bitte teilt sie.*\n> \n> Einer Gruppe ist bewusst, dass es auch Menschen gibt die gut Missstände wahrnehmen können aber schwer eine neue Initiative starten können, und hat sich auf Strukturen geeinigt die auch einfach Wahrnehmungen und Feedback entgegennimmt und das dann an anderer Stelle diskutiert wird und ggf. von dort Anregungen zu Änderungen kommen.\n\nThis message is not supported on your version of Mautrix-Telegram.
