I recently moved from a Fenix 6 Pro to Tactic Delta Sapphire Solar. Having had this set of charts for the Fenix ...

... I bought them for the Tactix Delta. Unfortunately, they will not install. While the Tactix Delta Sapphire is listed as a compatible device, the Solar is not. I was surprised by this as, with the exception of the solar glass, they are identical devices. I can only presume this is a miss on Garmin's part, and that whomever was responsible for categorizing the compatible devices either was not aware of the Solar, or just missed it. You can install these maps on nearly every device in the Garmin lineup.
Garmin support was not helpful, and so far, a refund has not been forthcoming. Any insight from Garmin or other users in how to address this? As a boater it would be nice to have my charts on the watch, and they worked on the Fenix 6 without issue.
Thanks.
