Hello Kari - depending on the recording length, it can take some time, but since it was last night, you should see it in your recording library. I'm curious as to your options for recording. There are two. First, you can record locally to your PC/Mac; secondly, you can record to the cloud. I've seen in the past that some users may have selected locally recording as the option vs. sending it to the cloud. That would be the first place I'd start.
For your reference, here is some additional information around local recording: https://support.zoom.us/hc/en-us/articles/201362473-Starting-a-local-recording.
