18362 is the build for Release Preview. You will not get a new build until the end of 19H2 at this point. You have two options. 1. Move to slow to get the next 19H2 build, or move back to fast for 20H1. If you choose Fast, there is a known issue with 18362.53 preventing it from updating to the current Fast build. There is an update to resolve the issue expected this week. Hope this helps.
