I see that you did ask before.
We are currently making improvements to EPG data ingestion for the set of Gracenote data that covers Portugal. This wiill get released once development and testing is completed.
There are gaps currently on some channels in the EPG grid where data is not available for some channels - eg as can be seen here
Please let me know post code and provider name / line up names in the drop-down that are relevant to you and will look into it when the improvements to to our ingestion are completed. We may need to refer some of the issues to Gracenote - but that needs to be very specific and checked out that it is not an issue at our end
