1 old generation devices are getting multiple critical reboots bugs since the last ‘stable release’ which was a month ago but they release 3 new updates for Fenix 8 in a week. I guess for Garmin you are not important if you bought an Epix Pro for 1200 euros so long ago, 2 years. They dead end Epic pro after 13-15 months, not the so called maintained is just a huge regression. My money will go somewhere else as Garmin customer service and support is a lot less then the prices they ask.
1 old generation devices like the Fenix 7 Pro and Epix Pro have been experiencing multiple critical reboot bugs since the last “stable release” a month ago, yet Garmin has released three updates for the Fenix 8 in a single week. It seems you are no longer a priority to them even if you spent 1,200 euros on an Epix Pro just two years ago. They have effectively hit a dead end with these models after only 13–15 months; what they call “maintenance” is actually just a huge regression. I will be taking my money elsewhere, as Garmin’s customer service and support are not worth the high prices they charge.
