为何现在公众号后台插入GIF无法实现超高清？之前我自己成功实现过Why can't ultra-high-definition be achieved by inserting GIF in the background of the official account? I've done it myself before

1. The same GIF picture can be inserted into the article before, but now insert the background prompt -- [pixel product cannot exceed 6 million pixels]? Links to previous articles: https://mp.weixin.qq.com/s/AJJZr5jSBJzj9ckhRxW0Iw (the figure photo in the text is in GIF format) 2 Why is the GIF image in the above article still clear after enlargement? Make another GIF in the same way, suggesting that the pixel exceeds 6 million. Cut the picture to reduce the pixels, which can not achieve the super HD effect of the above link?
