Why do I have to restart my AWU daily for it to stay synced?

For several months now I have to restart my apple watch ultra (gen 1) almost daily for messages to sync. It is connected to bluetooth, wifi, and cellular data. This is an unacceptable glitch it is having nearly every day. It will not send imessages, never tried with SMS which is quite frankly is irrelevant either way. Why won't the watch simply work as intended? It will give me notifications from new incoming messages but will not show them in the watch message thread. I have every update installed as soon as they become available with no beta versions. I try restarting both devices and nothing. I refuse to do a full factory reset because I should not have to deal with setting it up again when it should be working. real solutions only please.
