Black flash on transition to foreground

[SUPER_TOKI]

I have been talking about this problem since last year.
Is there anybody who can clarify this issue?
This is one of the things discussed in the past.

When the application resumes after suspend, a black screen occurs for several seconds.

When the application resumes after suspend(Keep suspend for about 10 seconds), a black screen occurs(average 200ms) Corona: Version 2019.3530 (2019.9.24) Xcode: Version 11.0 (11A420a) iOS SDK: iOS 13.0

In iOS, when the app is suspend(and waiting 10sec) / resume, the frames drop for 1~2 seconds

In iOS, when the app is suspend(and waiting 10sec) / resume, the frames drop for 1~2 seconds. And this will give the user a visually unsatisfactory app performance. Does this happen only to me?
