My husband has no problem with his s10 since he updated but I have same issue as u since I updated husbands watch wont work on my s9 we have the same watch but mine wont work on his mobile comes up with plugin keeps stopping on both mobiles but again no issues with his watch on his mob
I'm having same exact issue. I have the s10Plus and gearS2 watch. I've tried everything from hard reset on the gearS2 watch to un-installing and re-installing the the Galaxy Wearable app...I've done all this multiple tiems in the last two days but nithing fixes it. There are directions online to run watch in airplane mode and delete cached from memory, etc. NOTHING WORKS!
Same issue as everyone else. Ran the wearable update on Saturday and since then the watch has been unusable. Samsung support first told me to clear cache and data on both the Wearable App and the Gear S Plugin. I did that and still got the same error. I kicked it back to them and got a reply that they are moving my ticket to the Responsible Group, whoever that is.
Obviously no one did any regression testing
