But, it’s being a bit weird, it comes up with an error saying E2E decrypt privateKey - Serious internal error to decrypt Private Key.
This happens right after entering the same mnemonic used on your other devices, correct?
Can you also fill in some details about your environment - i.e. iOS app version and bits of the support template.
I have server side encryption activated, with the E2EE working brilliantly
Just to clarify: I assume you mean you have the E2EE app enabled. Server-side Encryption is distinct from E2EE. Or are you trying to use both simultaneously?
