In the game, open the ≡ menu and choose Report a problem. Describe what happened; the app adds the game log and a screenshot of the table so the problem can be replayed. It opens your email app, so you can read everything before sending.

Sign in with Google Play Games on both phones. Your profile, progress and settings are saved to the cloud and come back on the new phone.

Not yet. A browser version is on the way, which will also work on iPhone and computers.

In the app: Settings › Privacy and terms › Delete my online data. You can also ask by email; see the deletion page.
