Don't know where this belongs, but most "Accessory service" posts are here.
S21 phone and S8 watch. My phone is frequently giving me something similar to "Samsung Accessory service, tap for details." the link apparently isn't tapable.
A google search suggests insuring I have the most recent version. Google play shows "incompatible with your device."
Do I need Accessory Service? Is it incompatible? How do I stop the alerts?
