When I am going on https://keil.arm.com/mdk-community, in order to get access to a product serial number and instructions on how to generate a license from it, it appears the following messages:Something went wrongSorry, an unexpected error has occurred. We are looking into the issue.
Did you probably register at Arm later than the 18th of August 22?
In this case, the problem is related to a temporary maintenance issue
-> Arm's Service Team is already working on a solution - please retry in a few days, sorry for the inconvenience
I tried three different browsers with private and normal mode. But the result was the same. And yes I've registested my account later that 18th August.
I am in the exact same situation.
