Switching back fast to a channel previously watched doesn't work

#1
When I look at Channel X, switch to Channel Y, and then switch back to Channel X it doesn't start.
It says invalid password.
If I wait 15-30 seconds before I switch back Channel X works.

The issues is not with the iptv-provider as the issue doesn't happen with other applications with the same m3u-file.

Is it some kind of caschin-setting I can change to fix this, is it a bug, is it something else I can change in the settings to fix this?
