I think you’ve had a translation error… AD is rated Platinum (platina) not Silver (prata). 
There have been a few other comments along these lines…

It’s annoying that it isn’t working, but I’m on the fence on this one.
The reason that AMP is working now and AD isn’t is that, as a custom integration, AMP can push updates on its own timeline.You can’t really fault AD for the fact that HA does monolithic updates and bug fix updates are only put out once a week.
Maybe we need an Enshitification badge to go on any Cloud-based integration from companies known to do annoying shit like Amazon.
