SUMMARY The Documentation for Online Accounts seems to be out of date as it states "Note: does not work with Nextcloud" This however doesn't seem to be the case. I was able to add a Nextcloud account for Contacts & Files (Not for calendars and tasks though).
I'm sorry if this is not the right location to file documenation change requests. (It's my first KDE 'bug' report - I'm a recent MacOS convert looking to contribute where i can :)
Can you please point to the documentation you are looking at? I can't find what you are referring to
Oops. It's here: https://community.kde.org/Online_Accounts
Thanks. I've updated the page to be more accurate/up to date
Wow, these kinds of quick responses & fixes are a breath of fresh air! I'm looking forward to contributing more to the community!
