TTS doesn’t detect the image format and end up as UNKNOWN format during custom card creation.
The image i used are in .png: https://cdn.exburst.dev/cards/unionarena-na/UEX08BT_BLC-4-009.png
and with .webp: https://cdn.exburst.dev/cards/unionarena-na/UEX08BT_BLC-4-009.png?v=0a1ed6cd7a7c13ac&width=480&quality=88&format=webp
This also happen to now load any other image from this site. However if i save the image first and create custom card from downloaded file instead. It load normally.
