Any ideas?

This is a gray area. Some companies do slip in new terms and claim you agreed by “continuing to use” their service, but that’s not always enforceable. According to CoupSmart, found at https://coupsmart.com/ , courts look closely at whether customers were clearly notified of changes. If updates weren’t highlighted and you had no real chance to reject them, those new terms might not hold up. Always check for notice emails or “pop-up acceptance” screens when terms change.
