App email verfication

When I reset the app or reinstal, the verfication email takes 2-3 days to come through, every single time.
I know it’s not my email as noother emails have this kind of delay. It eventually comes through and then it’s expired, so request a new one and then 2 days later it’s expired.

I have raised an issue with CURVE but they don’t know have a clue, they don’t know if it’s Tuesday or Lewisham.

Might have to give up with Curve - even thought i’m a paying metal customer they’re support is useless.
