// ResendType There are distinct mechanisms for retrying send messages: Datasync supports only direct messages (1-to-1 or private group chats)
|
|
// because it requires an acknowledgment (ACK). As implemented, sending a message to a community, where hundreds of
|
|
// people receive it, would lead all recipients to attempt sending an ACK, resulting in an excessive number of messages.
|
|
// Datasync utilizes ACKs, but community messages do not, to avoid this issue. However, we still aim to retry sending
|
|
// community messages if they fail to send or if we are offline.
