Discovery Vitality - What are we paying for when apps don't work?

I have been unable to link my device to the app since Oct 2025. I spent time on phone and in conversation with a number of consultants trying to fix this. no one is able to help and each time it get escalated and I get told someone will be in touch and I am still waiting. I have been in contact with 3 consultants again in 2026, each telling me they will get back to me and now it is middle of Feb and no one helps. I am paying for a service with nothing in return. I see quite a few bad reviews, I wonder what Discovery is doing about this? They want to reward you for living healthier, but then their apps don't work. What a ****!!!
