### Bug description

On at least two independent Nextcloud instances, users complain about a reappearing message in their Windows sync client which I've sent via command line:
```
php ~/html/occ user:list |sed -E 's/.*- (.*):.*/\1/' |xargs -i php ~/html/occ notification:generate {} "Service downtime from … to …"
```
- Message can be set to read within the web interface. It stays read.
- Message is shown at each start of the sync client.
- Older/other messages do not reappear in the sync client.

I have sent this message with Nextcloud 26 to notify users about the update to Nextcloud 27.

I have found mentioning of this behavior with Google, but no definitive solution. Thus I think this is a bug of sorts.

**Note:** I'm not sure if this is a bug pertaining to Nextcloud server, or the Sync client. I have no idea how to check this.

### Steps to reproduce

1. Send a message to a user with `occ notification:generate`
2. Connect Sync Client to that NC instance
3. Message appears in Windows Notifications
4. Dismiss message
5. Reopen Sync Client
6. Message reappears

Optional:
1. Connect/login to NC Webinterface
2. Mark Message(s) as read
3. Reopen Sync Client
4. Message reappears

### Expected behavior

After showing the message once via Windows notifications and being dismissed by the user, it should no longer reappear.
