Users share the same database

I recently launched my app five days ago and discovered that my users are sharing the same database. Where did I make a mistake, and how can I rectify it?

thanks

How are you restricting data between your Users?

(Obviously, you aren’t…

so you need to…

primarily by setting up Privacy rules, but also maybe with appropriate search constraints, depending on what you’re actually trying to do).

i found a video in yt, may i ask if this is correct.thanks

i follow the said video and it works, i guess you have the same idea with the video.

thanks for the help.
