9 months ago @irqnet - I believe I have exactly the same issue:
- Messages to individuals work flawlessly.
- Messages to newer WhatsApp groups work flawlessly.
- Messages to older WhatsApp groups don't work at all.
The groupID (also chatID, remoteJid) look different in newer WhatsApp test groups I've created than from older WhatsApp groups I've been a member of for a while:
- Older groupIDs (extracted from messages to the group sent by someone else) seem to be in the format of 4478494xxxxx-15883xxxxx@g.us (my mobile number followed by a '-' followed by some other id).
- Newer groupIDs are in the format of 1203632033628xxxxx@g.us and work every time (with or without the trailing '@g.us')
It looks like it is only possible to send messages into groups, which have been created by the WA account, that is used in NodeRed for whatsapp-link.
So actually I'm trying to post messages into groups where I've been invited to, even if I have admin privileges or not (doesn't matter), messages send from chats-out to the chat-id of the group, do not arrive/appear.
Trying so, with chat groups I've created on my own, the message immediately appears in the chat.
