We have discovered error with downloading and displaying branding image logo in the IM clients, in Bopup Messenger starting from version 5.4.10 and in Bopup Observer version 4.3.10 and higher. This issue relates to incorrect detection of a client version on the communication server so the logo is not delivered to the messenger. This may cause errors and issues with establishing connection on the messenger startup.
This issue also has an effect with updating IM client versions from Bopup Communication Server. This is a server-side error and it will be fixed ASAP.
