Too many saves (replays)

When I tried saving a replay I got a message saying too many saves, I’ve only got 10 saved replays, is that really the limit?

Yes, as posted numerous times here. The Replay Limit is 10.

Thanks, googlet it, but couldn’ find anything.

It should be UNLIMITED to save replays until you run out of storage on your Xbox One hard drive.

Here are pages and pages of previous threads and posts from a Search result regarding only 10 saves in Forza Motorsport 6:

Instead of starting yet another thread on the same subject, it is a good idea to Search first:|5
