The function of uploading videos by Pinduo needs to use the latest version of Pinduo APP, because the old version of APP may not support the function of uploading videos or there are compatibility problems. According to the official news released by Pinduoduo, in early 2022, Pinduoduo has upgraded the video uploading function of the APP. The new version of the APP is more stable and smooth, adding some practical tools and special effects, so that users can make high-quality personalized video content more easily.

Therefore, if you want to use Pinduoduo's video uploading function, I suggest you download the latest version of Pinduoduo APP, V7.79.0 (as of March 27th, 2023).

It should be noted that different phone models and operating system versions may have an impact on the compatibility of the APP. If there are abnormal situations such as flashback, jamming and black screen during use, it is recommended that you first check whether the system and APP versions have been upgraded to the latest version, and try to clean up the cache and data, or restart the device before trying to use it. If the above methods still can't solve the problem, then I suggest you contact the official customer service in Pinduoduo or the forum community administrator for more detailed help and solutions.
