Clearing Logo Image Cache

I replaced a few channel logos, but the URL and filename remains the same in my M3U. Channels seems to be showing a cached version of the old ones. How do I get channels to show the updated logos without having to rename them? I'd delete them, but can't find them.

From the web admin, to go "Live TV & DVR". Under "Guide Data" click the gear icon and choose "Refresh Station Logos".

That didn't work. The correct logo shows up on the web interface TV Listings, but the old one still shows on the app TV Listings.

Edit: Still showing phantom logos. There must be some way to delete them.

Does anyone know were these are stored?

It's probably a url in your m3u? This happens when different images are in m3u file vs xmltv file

The URL in my m3u's tv-logo tag points to the correct file. If I open the image directly, the updated logo is online.

Channels still shows the custom ones I deleted and are no longer online. They still have the same file name, so I'm guessing they're cached somewhere. I could just rename them, but I'd prefer not to since they're also used elsewhere.

Does adding ?v1 to the url help?

No. That just broke the link and Channels showed no image.
