Thanks for the nice update but the images fetching not works. On the same feed using the old widget code I see the thumbs, with latest code I don't.

I just uploaded v1.1.3 - image fetching should be more reliable now.

Great, thank you. I'm testing it and this update works fine. Now the widget is amazing.
I would suggest only another thing: the date is in US format, I mean Month/Day/Year, but if you disable the 12h you should live/use EU time/date, so display the date in Day/Month/Year would be more useful! Not a big trouble BTW. Thanks again!

Thank you! :)
Currently the date is tied to your system language, but maybe I can add an option to set the locale via a parameter. I'll look into it.

@Saudumm

since the last update of the Scrptable app I have problems to use your Skript .

Can you check if you need to update something ?

Hi! Great work. Do you know why it does not work with “https://ilpost.it/feed” as source? Thank you.
