Camera preview takes time to open in ios after capacitor 3 upgrade

**Describe the bug**
I have been using this plugin for a while, but recently we upgraded from capacitor 2 to 3 and upgraded the plugin to v3 and while things work as usual in android, we have been experiencing some delay while opening the camera preview in ios. Specifically, on clicking on the camera cta, we see a black screen for a while and then the camera preview opens after about 2-4 seconds. I've tested this on iphone 6(ios 12) and iphone XR(ios 15) and facing this issue in both the devices.
And like I said things work fine on android devices
