My Samsung Watch 4 no longer displays my messages in full since the last update a couple weeks ago. All I get on my watch now is a notification that a new message has been received.
Recheck your settings for notifications in the Wear app. Sometimes updates move settings so things get turned on or off. Open the Wear app. Go to Watch settings/notifications/advanced settings and toggle on show details automatically when checking notifications after an alert. Regardless, you should still get the details when you tap on the notification card. Also, clear the watch's cache partition.
I've had this and a few more issues after updating my watch 4 classic. I regret updating it. Only solution is waiting for Samsung to push a fix update to address these and other issues.
Aside from the truncated notification (which can be changed in the settings), what other issues are you having that you believe that Samsung needs to push a fix for?
Wrist detection does not work. If enabled you will have to keep entering pin/ pattern once screen goes dark.
Knock knock gesture issue after power down. Having to toggle the feature off then on and re-selecting the app to associate it with in order for it to work.
Battery drain with no way of checking app battery usage. Somehow the tab when selected never shows any app usage when before it did (watch 6 issue as well)
None of these issues improved after multiple cache partition clear and resets.
