As discussed, my friend. The whole job was completed with the app. Notifications on the app worked until the ios certificate got expired, which is normal for every app on the ios app store. Also, I explained I was on a vacation for health reasons and as you requested, I gave you the guide on how to generate and upload a new ios push certifcate on One signal. Meanwhile, if you still have other non-app related concerns for your una site, I will be back pretty soon to help look into them. Warm Regards

In addition, did checked on your messengers for both apps and works fine.
