I am writing to bring to your attention an issue I am currently facing with my point of sale system. I have been trying to add new products and categories to the system, but I am encountering a problem where the items do not show up on the product list despite clicking the save button. Instead, I receive a message stating that the system is loading data from the server, and nothing happens after that.

I have tried adding different products and categories multiple times, but the problem persists. This issue is causing inconvenience as I am unable to update my inventory and make sales.

I kindly request your assistance in resolving this issue as soon as possible. Please let me know if you require any further information or clarification from my end to address the problem.

Thank you for your prompt attention to this matter.
