Group Members Not Updated

[webatspeed]

I followed Getting Started and then created a group chat. Multiple users have joined the chat via invite link, but the members information only lists me. Thus, when sending messages via API, only I receive the messages in the group chat. When using the iOS client, everything works fine. What's wrong?

curl 'http://domain/v1/about'
{"versions":["v1","v2"],"build":2,"mode":"native","version":"0.95","capabilities":{"v2/send":["quotes","mentions"]}}

curl 'http://domain/v1/receive/+49xxxxxxxxxx'
[] // lists info like "Received a sync message" on first call

curl 'http://domain/v1/groups/+49xxxxxxxxxx/group.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
{"name":"","description":"","id":"group.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx","internal_id":"xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx","members":["+49xxxxxxxxxx"],"blocked":false,"pending_invites":[],"pending_requests":[],"invite_link":"https://signal.group/#xxxxxxxxxxxxxxxxxxxxxxxxxx","admins":["+49xxxxxxxxxx"]}

curl -X POST -H "Content-Type: application/json" 'http://domain/v2/send' -d '{"message": "Test via Signal API!", "number": "+49xxxxxxxxxx", "base64_attachments": ["'"${TMPFILE}"'"], "recipients": [ "group.xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" ]}' // only one recipient inside group chat

Did you call receive after the others joined the group? (In native/normal mode you need to call the receive endpoint regularly - so, if there's no specific reason for using the normal/native would I'd suggest to switch to the json-rpc mode instead.)

Yes, I did call receive well after their join multiple times until the response went from sync message to []. As a temporary workaround, I restarted the container with a different volume. (A normal restart with more receive calls wouldn't do.) Anyway, starting it in json-rpc mode later on solved it also with more users joining the group. Thank you.
