There's a bunch of issues with this feed, and one of them is the lack of titles.

Wow, alright, that explains a lot.

Interestingly when adding just the URL and checking the "autodiscover" box, the feed is correctly added - but it seems to discover the Atom feed which then works: https://electronupdate.blogspot.com/feeds/posts/default

Alright, thanks, feel free to close!
