How to manage Chrome sync data? (Like delete something?)
Solution 1:
I was able to solve my issues by cleaning up the settings on one "master" chrome instance, setting everything the way I wanted it to be. Then, I went to Google Dashboard and cleared all Chrome Sync data from there. It takes a few minutes, refresh until it says everything is empty ("Nothing to see here"), go ahead and sign in to sync on Chrome. Now everything should be good. Just try not to add stuff you dont want from now on, like syncing to your account on an instance of Chrome which has a bunch of settings you do not want.
Solution 2:
To delete sync data from chrome is easy you have to actually Delete sync data from Google Dashboard.
Just go here and delete sync data. this might take a some time.
Try to sync again, login again in chrome with your google data
