Hi guys and girls,

we used an Addon called WhisperInvite for raidinvites. The Addon is a little bit older but still worked until the end of BfA.
It stopped working for guildchat with shadowlands. Short google brings me to a thread from beta where they talk about addons accessing guildchat are broken because of Blizzard.
I tried to dig deeper but couldn't really find any information.
Did Blizz change the API for guildchat and are there any information about it?
