You mean this?

[r3pek]

You mean this?

Yes. Also, the NextCloud client reports an update to "Array" instead of "Passwords"

[marius-wieschollek]

I think nextcloud parses the info.xml to get the name. The info.xml also allows translated values and while the app store respects this, other parts apparently don't.
