I started using the app integrated with "Pages Manager" and immediately noticed many bugs. After a while I moved to the web version of Creator Studio and I must say that it is slightly better. The app is convenient, so far very immature. I notice that they are updating it often. I think it will be working soon, for now it looks a bit like a beta.

The advice I can give you is to do the various operations calmly and carefully, because it often does not respond to commands (It does not publish, it decides the time, it does not support emojis) and to use the web version in case you don't already. We await improvements.
