There is a patent acceptance notice and it is the same application date. Why can't some people find it online and some people can't find it?

Applications with the same filing date may not be made public on the same day. If they are not made public, they cannot be seen on the Internet. If they are utility models, inventions and designs, the processing flow of the application is different, and the time from application to publication is different, depending on the specific situation. The general utility model and design may take about half a year, and it will take longer if it is an invention.
