nextcloud

I have a subscription of Family and Friends on the site tab.digital. This would allow me to add apps to my nextcloud. One of the apps I have been most excited about has been the News app, which can administrate open subscription feeds like RSS. However, I have a couple issues.

First of all, I've been notified that the app is unstable on my Family and Friends subscription from a dialogue box. I don't know if that is due to me having the wrong subscription or whether it has to do with the app itself being unstable.

So far I've ignored that warning, because I can risk the service failing. I'll just have to contact the provider to reset in that case.

I have sent an email to the provider, but I expect an response on monday so It's kind of long to wait.

Does anybody have any experience with News app on Nextcloud or with tab.digital?
