Episode number not mandatory for "serial" podcasts
I have a serial podcast where I forgot to set the Episode number on two episodes. The RSS showed those episodes without a number out of order. @yassine "Episodes are ordered by descending season number and ascending episode number when podcast is serial (given they have one of those specified). They are ordered by descending publication date when episodic."
SO I guess, we need to make sure that episode numbers are mandatory when setting a podcast as serial.
