Thank you for your answer, but my game will not be released this year, I am just testing it in advance, if you plan to update the network status in the future, I am very happy to look forward to it.
In addition, I also had a BUG during the test, I am not sure if it is, when the download progress is 100%, the OnDownloadFailure event is executed, but I forgot to print the message, so I am not sure what the problem is, it Only appeared 1 out of 10 tests.
