I recently switched from a Google Pixel 6a to a Pixel 9a, both running GrapheneOS. I was able to register my Pixel 6a device with both the CIBC & Simplii Financial apps (essentially the same app) but cannot register my Pixel 9a with either app, receiving a "Sorry, we can't register this device. Sign on with a different device and try again. (6086)" error. I have tried every solution I have found online and everything I can think of to resolve this issue. I assume others are still experiencing the same issue so I'm hoping to breathe live back into this thread.
