Some useful things to know
Why am I asked to sign in again to my account?
Whenever a time interval (about 20 minutes) has passed, you'll be asked
again to sign in to your HTC Watch account before you can continue to
rent or purchase videos or access some settings. This is a safety precaution
to check your identity and to ensure that you acknowledge that it is your
account.
How long is the rental period of a video?
Depending on the studio's terms and the country where you downloaded
the video, the rental period is either 24 or 48 hours, starting from the first
viewing.
If you're not immediately watching the video, you have up to 30 days
before the rental expires.
Why won't HTC Watch allow me to remove a device and add a new one?
Removal is available once every 120 days when you've already reached the
maximum of five HTC devices in your account.
How do I remove my HTC Watch account from my device?
1. In the Watch app, press MENU
2. Tap Remove account.
You can also go to Settings > Accounts & sync to remove your HTC Watch
account.
and then tap Settings > Account.
