Constants on legacy devices

Hi guys,

currently I am analyzing issues with my apps occurring on legacy devices (Fenix 3HR, Vivoactive). It seems that those devices do not like when constants are defined in class context. My code is a very simply one, defining a constant on class level and then using this constant with the class prefix. Even in the same class accessing the constant is not possible as the watch crashes with "Symbol not found" error. Interesting thing is that with never devices like Fenix 5 no error occurs.

Is there a limitation in old firmwares concerning constants?

Thanks!

Bye
