nextcloud is a rip off anyway. "dislexia friendly font"..."client side encryption" ..."local storage" paying over 1000 euros a year for that spin, are you f'king kidding me???
I pay $17 AUD month for Office 365, get everything next cloud adverstise and a lot more! Even Adobe Creative Cloud is a better option for many online based businesses...
change to office 365 you would be far better off!
