As a relativily new user, how long does it usually take for features that are available in the USA to be made available in the UK?
Whisper Mode and Ring Doorbell alerts have been available for about a month now in the US.
There is no set time for these things, eg weeks, months . . . . . . . Also some features might never appear in the UK. Generally it also seems that Amazon's Customer Service reps do not have any information about such things.
