Worked on older Android. Will not work on iPhone 7 – Callmask - Free Private Number for Texting and Calls Review

I had his app on my old galaxy S5 and it worked back in 2016. Reinstalled recently on my iPhone 7. Worked after a couple of tries, and now the “loading” indicator just spins and spins, never making a call. I’ve also had instances where it will start to call and say “call failed” when I have full service and can receive and send callas and texts with my regular service. Every time this happens, I get deducted time off of my call mask that I purchased. Receiving “error connecting to server” as of late. Don’t know if the creator is a hobbyist or a full developer, but the app is definitely lacking. Disappointed in functionality issues and being charged for non-working technology.
