appodeal adsRequest, event.phase does not return "displayed".

Corona Marketplace Appodeal
#1

Hi,
When an interstitial advertisement is displayed, event.phase does not return “displayed”.
“init”, “loaded” and “clicked” work correctly.
Can you find the cause?
I am testing against version 2023.3688.
This problem does not occur on Android devices, only on IOS devices.

local platform = system.getInfo("platform")
local appodeal = require("plugin.appodeal")
local appodeal_appkey = {
	android = "XXXXXXXXXXXXXXXXX",
	ios = "XXXXXXXXXXXXXXXXX"
}

local function adListener(event)
	print("event.type", event.type)
	print("event.phase", event.phase)
end
appodeal.init(adListener, {
	appKey = appodeal_appkey[platform],
	supportedAdTypes={"interstitial"}
})

timer.performWithDelay(5000,
	function()
		if(appodeal.isLoaded("interstitial")) then
			appodeal.show("interstitial")
		end
	end
)
