[Update] I encountered the following issue:
I once had a website.
It functioned well, except when opened in a new tab with target "_blank."
When accessing the site directly, everything appeared normal enter image description here
However, when accessed via a new tab, the buttons at the bottom were covered. enter image description here
I assumed it was a viewport issue but I am unsure how to address it.
Can anyone offer suggestions on how to resolve this problem?
