I meet specs but Zwift runs at about 2 fps

Firstly some praise. The Android app menu screen runs pretty well and it discovers my devices.
However when I run the app the frame rate just chugs at about 2fps. I previously used a PC with Windows 10, which was streets ahead.
My specs: Android 10, AArch64, 64bit CPU 8 cores, opengl es 3.2

Can you please identify your device?

Ulefone Amror X5
Armor_X5_Q

Seems decent enough.

But no real idea.

Anyone?

Gave the app more permissions and did a restart, seems much better.
