That’s an interesting way to describe a lack of configuration on your part.
Imagine me saying: "The major shortcoming of Google drive, in my opinion, is that that it's not able to sync files from my phone. There is some workaround involving an app called 'Google drive' that I have to install on my phone, but I haven't gotten around to it. Other than that, Google drive is absolutely fantastic.
I don't know why the sarcasm is so necessary. I very much enjoyed Nextcloud and I proudly ran it for the better part of a year. I even ran various NC-ecosystem apps, such as the Office ones. However, my objective was to try it out from the standpoint of regular self-hosting. I wanted to contrast the 'out-of-the-box' experience to Dropbox, which I had been using for many years up to that point. Yes, one was centrally hosted, while the other was self-hosted, but still, that was the experiment I was running. So I'm sorry if I didn't live up to your standards of what a user should be doing to their software, but I sure had lots of fun self-hosting tons of software at that time.
