Communication problems Service Creatio App - Self Service Portal

Hello,

We are having issues establishing communication via Self Service Portal.

- Messages posted by a customer via Self Service Portal are not visible to agents via Service Creatio app.

- also vice versa, messages posted by agents are not visible to the customer on the Self Service Portal

- Customer can upload an attachment file on the portal, but it system shows it as uploaded by "Supervisor" (this is the only type of message that is visible on both sides)

We are using the demo environment and the issue persists on Classic UI.

Version: 8.0.10.4735

Did anybody else encounter such problems, is there a known solution or a workaround?

Thanks in advance and best regards,

Mislav Rozić
