How can I zap back to history when watching IPTV live channels ?
Zap History should be available on all images and it should work on IPTV channels too.
When you play a channel from the system's Channel List or bouquets, it will be added to the history (this assumes that Zap History is active).
However, if you play IPTV channels from AJPanel tables, they will not be added to the history.
