Linked services using the new architecture do not require edge drivers.
However, there are still a few left over from the old architecture which used a combination of a groovy smartapp and a custom DTH. They have to be replaced with new endpoint smartapps, so anyone who’s using one should get in touch with the source where they got the original from to find out what the update options are.
The original garadget integration was one of these. I don’t know what the replacement is, if any.
Definitely don’t delete anything until you know what the replacement will be. You won’t be able to reinstall it.
