Many of our friend using /e/ on different devices has found what is my experience.
I tried to install many Banking / Finance / Authenticator / Wallet application on my /e/ official but all these applications say “The device is rooted” (Though my device is not rooted).
I think there is something at the base of framework of /e/ due to which this error comes.
I think if that is cured then all will be able to install these Banking / Finance and other security seeking application on that devices.
I think this is what needs priority. It is very much essential.
