The watch audio transmission progress was not obtained
没有获取到进度，一般是在传输过程中，应用被杀死，重新打开后，App没有获取到传输进度。
此时传输并没有被取消，还在传输队列中，当传输条件达到后，系统依然会自动向手表端传输文件。
而且此时也无法取消传输，只能等系统完成传输，也不要重复进行传输，这样会导致传输两遍到watch端。
一般播放音频时，传输就会继续进行，完成后，手表端和手机端都是显示完成状态。
No progress is obtained. Generally, the application is killed during the transmission process. After reopening, the App does not obtain the transmission progress.
At this time, the transmission has not been canceled and is still in the transmission queue. When the transmission conditions are met, the system will still automatically transfer the file to the watch.
And at this time, the transmission cannot be canceled. You can only wait for the system to complete the transmission. Do not repeat the transmission, which will cause the transmission to the watch twice.
Generally, when playing audio, the transmission will continue. After completion, both the watch and the mobile phone will show the completion status.
