Trying to change phones, using the activation with another smartkey just gives error "something went wrong". It does not state what went wrong and now it is not possible to activate on website.

I got blocked by the bank for no reason, then as part of unblocking I had to update the smart key app to this v 3.18.0. It gets stuck during activation - the activate button does nothing just spins the hourglass. The older version 3.10.0 worked fine. The bank staff says the only option to fix this is to upgrafe my phone. I figured it's more economical to change the bank... These banking/key apps are a nightmare, plus not any more secute than sms, but I guess they need to genetate jobs.

Hello, we are sorry to hear about your review. The app undergoes regular updates that need a certain version of the operating system. The main reason is security. We try to perform updates in exceptional cases, and only due to legislative regulations, installation of security features or bug fixes.
