The system is very slow

I have a problem with saving and also the system is being very slow. Here is the screenshot of the number of pages that I have and the error message that I am facing. Is the problem can be due to the high number of pages that I have. I am thinking now that maybe I need to change Appgyver by another no coding apps maybe it does not support the size of my work. Thank you!

Hello @Yosser_Kammoun, were you able to continue developing the app or is this error still coming up? Even if you have many pages, you should be able to save.
