Question Google Play - Slow Warm Start Rate

Google Play has recently started warning that our games are having a high Slow Warm Start Rate and according to one of their blog posts this affects the store ranking.
I've tried looking into it and it seems that those TTID (time to initial display) events are fired before our game actually starts loading, so it's probably the time that the engine takes to start.
Is this assumption correct?
Is there anything we can do to improve it?

 

I am having the same issue with 2020.3.33f1

 

I have the same problem with 2021.3.3f1.

 

We're having the same issue. TTID is counted to the point Unity displays it's logo. So it does not look that something can be done.
Have you found any solutions to this?
On our side, the Slow Warm Start Rate is on ARM Cortex-A53 mainly.
Thanks

 

Is it allowed to display any image to counter the issue just before unity splash? Just thinking why not have a custom activity which displays game's logo/splash and from there it launches unity. But not sure if unity terms has anything to do with this hack.

 

So far we haven't found any solution to this. We did think of some workaround like @Voxel-Busters suggested, but we're not sure if it's worth it or how we would achieve it.
Would love to have some official answers on this.

 

same problem with 2021.3.10f1.

 

It's actually getting worse - especially on larger devices
