It seems that the bookmarks get synced but my themes do not... I already have ensured that under the settings, the themes checkbox is checked. I referred to this: Syncing Google Chrome. What else need to be done?
Do the following on every device using chrome.
- Disconnect your accounts from chrome. This can be done in "settings" / Sign in options
- Clear all settings from the beginning of time. "tools" / "clear browser data" / check everything, and select from the beginning of time.
- re-sync your account. Choose whatever you want. I like to sync it all...
- Close chrome once sync is done.
- Sync in to another device. (again, make sure you follow steps 1-3 on all devices)
- Try theme changing.
Note that this will only work if theme was installed from the Chrome Web store
