Hello.
When attempting to play content on the IMA sample site (https://googleads.github.io/googleads-ima-html5/vsi/) using the following procedure on an iPad Safari,
The main video does not play, and the audio of the ad is played on a black screen.

I was going to attach a reproduction video, but could not due to size limitation.

Spec:
iPad Mini(iPadOS 16.6.1)
(Could not reproduce on iPhone.)

Reproduction rate:
60%.

procedure:
1. Open two tabs and use one tab to access the IMA sample site. (https://googleads.github.io/googleads-ima-html5/vsi/)(00:00~)
2. Press the VAST tag “Sample” from “Input type” on the IMA sample page.(00:07~)
3. Press "Test Ad" and go to another tab that was initially opened before the preroll was played.(00:13~)
4. Wait until preroll finishes.(00:15~)
5. After the main video starts playing, move for the tab where the IMA sample is open.(00:31~)
6. The main video does not play and only the preroll audio is played on a black screen.(00:34~)

Hi pineapplevine1,

We have tested on a simulator and were able to replicate the issue. 
Kindly let us know, whether this is happening on a physical device ?

Hi,

It appears that the issue you are encountering is likely a P4-type issue, which may be caused by settings within your operating system or browser. However, it is important to determine if this issue is truly preventing you from rendering IMA ads through the IMA SDK. It is imperative that we prioritize resolving issues related to ad serving blocking. Should you encounter any such difficulties, please do not hesitate to contact us once more.
