(Please forgive my poor English.)
Telegram's image groups contain up to ten images, but the images in a group of ten images sent by the client are leaked and only appear in a certain number of channels.
After a lot of testing I found out that this is probably a Telegram server problem, it doesn't matter about the sender or the client, as long as the group is sent in that channel it will definitely leak; as in the attached P1, this is the normal state after sending, but in the real case (web version or other clients that receive this message for the first time) it is the case of P2, where the pictures that should be in one group appear in the other An image that should be in one image group appears in other image groups.
In some channels it has reached the level of 100% reproduction, for a sample of the problem see my message: https://t.me/s/cxplayworld/565
I'm currently looking for a temporary solution to this problem, and found that sending groups of images to a timed queue via timed messages and then sending them to the channel using "Send Now" avoids this group leakage problem.
Steps to reproduce
Send a group message with ten images in the problematic channel;
Copy the direct link of this image group message and replace it with a preview link;
Enter the converted preview link in the browser and observe that the image group is split into multiple groups.
