Does the latest system solve the problem that third-party apps are inaccurate in obtaining mobile phone space?

Still using old system 17.3 No matter what software, plugins have encountered space calculation error problems Today I stuffed movies into my phone and uploaded files on the web page for a while, but the app told me that there was no space. I went to the system to see that there were still more than 20 gigabytes. It seems that Apple's third-party app is often inaccurate in obtaining mobile phone space, and the delay is very large I don't know if the latest version of the system has solved it
