Unfortunately, they haven't answered to our letter. The plugin was not show warranty options on the Product page and in google console, we have faced 503 error msg connected to pearcare code.
We downloaded this app looking for a way to offer a warranty that we can fulfill, the name reminded me of AppleCare so just went with it. It isn't perfect, at the moment I've had to use some of my own CSS as the design tab is a little bit lacking but still, it does work perfectly for us.
Customers can buy the warranty protection easily which we now track.
