Hello Tin,
I conclude from the fact that you do not answer that the problem is not sitting in front of the monitor. :-)
If there is no problem with Edge, Chrome and Firefox, it is Safari. Safari probably does not accept hidden download.
It's probably a security issue. I guess everyone blames the other.
The old versions of Safari accepted the hidden download.
The problem only occurs with newer versions of Safari.
Thanks,
Michael
