Custom Action -> Trouble on Android

My app’s URL: app.weeklystyle.de

Under windows 10 with chrome everything works fine.

On my pixel 4 (android) with chrome it seems that a custom action is fired twice from time to time.
On my huawei (android) with chrome I can’t open my publish to pinterest link since two days.

Very strange.

Any one else have this problems?

I can see the pinterest app in the background but if I tap on the pinterest app it disapear.
Perhaps a bug on the pinterest side…
