User Handling Admin and user accounts

Hi all,

I have a general problem, which I was not able to solve so far. I have three users, Admin, A, B. As I started working with nextcloud, I just used the Admin Account to synchronize all my data folders including photos and reiceips. Now as the project is growing, I`d like to use A and B to synchronize all data to one PC. Where each user can use nextcloud also on his own smartphone. Both user should access the same data and should have the possibility to synchronize some own folders. Also I think it is more secure not to use the Admin account for daily work, but only for some configuration related stuff. I think the idea is pretty basic, but I didn’t understand how to do it. If I synchronize also User A to my PC, no data is synchronized, even if all data is shared (read and write). Are there other ways to transfer all the data from Admin to user A and B?
