Validating an rss feed
If your shows are all connected to your profile’s brand and identity, then it’s better to directly submit your profile’s feed.
I am struggling to get this feature to work :( " Podcast artwork must be between 1400 x 14 x 3000 pixels, JPG or PNG, in RGB color space, and hosted on a server that allows HTTP head requests." I have uploaded an image 1400x1400 as my profile and it is a Jpeg type, 262KB size.
their Feeds normally work OK, and all I can advise is you look round their settings and see if you can find a way to restore the feed.
I have setup multiple triggers by using IFTTT that trigger actions based on my RSS Feeds. action=rss), I get a "Sorry, this feed does not validate", and shows me all of the errors.
Unfortunately, Feed Validator can be a bit persnickety about small details, and it will show a feed as being invalid when the feed is actually fine.
Unless you're having some kind of other trouble with it, I'd say you're fine.
