Samsung gear app stuck on Update dialog and disconnect from my gear s3 frontier!

I have gear s3 frontier and I connect it to my galaxy s7 edge phone. It works great but for last 2 weeks when I open samsung gear app in my phone it show a dialog with this message: > Notice > > A new version is available. Update the app to continue I can't ignore it and the only option I have is to press the Update button. After that it show a screen that say : > Preparing to connect ... When the progress bar complete, the app close automatically and disconnect the watch. I checked "google play" and "Galaxy Apps" but there is no update available for "Samsung Gear" app. and currently I can't connect my watch to my phone. The solution I tried to fix this problem: - I tried to uninstall Samsung Gear app and install it again with google play. It worked for few days but after that I have the above problem again - I use the option of "Connect to new phone" on my watch. It factory reset the watch and connected my watch to phone. But again after a few days I have the above problem. How can I solve this problem. I seriously offended because both of my phone and watch was Samsung flagships but they can't connect to each other. If I can't solve this problem I will throw away my phone and watch and I will buy an iphone x with apple watch.
