Universal Links Weirdness in ios 14

Could anyone explain to me this weird behaviour on ios 14:
AASA:

Code Block 
{
	“applinks”: {
		“apps”: [		],
		“details”: [
			{
				“appID”: “2JRXN3SX2L.lt.pigu.pigu”,
				“paths”: [
					“NOT /*/users/*“,
					“NOT /*/u/*“,
					“NOT /*/auth/*“,
					“NOT /*/orders/payments/hubhandle/*“,
					“NOT /*/orders/payments/handle/*“,
					“NOT /orders/payments/hubhandle/*“,
					“NOT /orders/payments/handle/*“,
					“NOT /*/o/app/*“,
					“NOT /o/app/*“,
					“NOT /*version=full”,
					“*”
				]
			}
		]
	}
}

Entitlements:

Code Block 
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">

	</array>
</dict>
</plist>

App bundle:

Code Block 
 lt.pigu.pigu

Links with click.email.pigu.lt domain (password reset, like: https:// click.email.pigu.lt/?qs=0b41cb0f7e00550a8ed1ad655977ebe71ff54138701a61c87d1c50e572776b217272de7cda7c4fe0a8df9df3060a5c4a0cff21828855d875) work just fine. They open directly to app.
Now pigu.lt domain links (like: https:// pigu.lt/lt/kvepalai-pigiau/kvepalai-moterims/tualetinis-vanduo-dolce-gabbana-3-limperatrice-edt?id=538670) act weird.
They open in web and then apple banner drops down to suggest open it in app (clicking on it works fine). But only if app is from appstore. With dev builds/fastlane builds banner suggest downloading app from appstore.
click.email links work fine with all versions.
If I long press on click.email link it suggest opening in web and app.
pigu.lt link - only open i web.
Universal links works fine with ios12.
AASA validator says everything is fine.

Any ideas?
