This is what I do. As soon as I open the space, I will automatically go to my personal homepage. There is a saying "What am I doing ..." Type the signature you want, and then select "Update to my qq signature at the same time" below. I don't like being at the top of the latest trends in the group, so I often do this and it always works. Let me show you a photo. You and I both think it can be done.
