One of our professors reported that his students thought his modules were locked because they saw 'locked until' notifications under his modules in the Canvas app. When we looked at his modules using a browser, it didn't appear that any of the modules were locked. We could only see the lock until dates when we clicked on edit module.
It makes sense for 'locked until' to not appear when the date passed, but the behavior in the browser is not consistent with the behavior in the app. Maybe we can make it consistent?
