Yes correct, personalized settings get lost, it happens in Ipad tooI think FTS doesn't support Zee5 completely bcoz it's working fine in other platforms...Even we can't set language or some settings ...Every time it doesn't save our personalized settings...
Well instead of logout and login it's better to directly to see app there select live channels...
Yes, We can watch channels in app itself but The whole point with channels syncing is to have seamless and integrated live tv experience in FS interface itself.
Again in app itself, your preferred channels goes missing because it looses personalized language settings and you have to apply language in filter to see those channels.
