I've been using JW for my Roku feed for a couple of years now...no problems. I added a video today like I usually would and suddenly have:

The feed format is invalid. We are unable to parse it.

I've tried re-uploading the newest video with a shorter filename...changing the title to remove the atypical character "|" (character above the forward slash. Still...feed won't work. Feedbucket has no problem reading the feed.

[size=85]Can't figure it out. Any help would be appreciated![/size]

Your feed file does not look like it conforms to Direct Publisher's MRSS spec.  You've got several tags that the spec will not recognize.  Did you forget a flag/switch when exporting the feed file?

I've had emails back and forth with JW on this issue and still haven't found a resolution.

They've suggested I try using https://cdn.jwplayer.com/v2/playlists/bvnULZlM?format=legacyrss&poster_width=1920

It seems to contain the same info. I'm still not seeing a problem. 

Anyone else having issues with JW feeds?

The same issue is back. This recurring problem seems to be on Roku's end. It self-corrected after days last time (explained above). 

I added a new video to the channel last night...exact same type of thing I've been doing for years (just like when this problem came up a few months ago) and the channel now shows errors again! 

1 item has an error: No valid items were found in the feed: validate09/18/2019 10:33AM

-->The error is 137060.pending.en99 items have error: 

Thumbnail must be 16x9 aspect ratio, at least 800w x 450h, and either in JPG or PNG format.

-->ALL images are 16x9 and over 800w x 450h jpgs (and this error didn't show until the latest upload)
