Thanks the info.
The digital dialer 2.12 is a newer version than 2.2. The version you have loaded is version 12 the one you’re attempting to update to is version 2. We generally allow for older firmware to be loaded, but in this case due to the version it is not allowed. Apologize for the confusion. I will remove version 2 as an option from the site. This will still show in your mobile until you clear saved data.
