Just a note that I noticed the "Continue Session" is active and not greyed out upon installing and opening the mac app for the first time (having deleted the Studies folder in the ~library/containers directory before reinstalling). Of course this doesn't appear to be a big deal, but I mention it in case somehow it could cause an unexpected issue somewhere else in the use of the app down the line, or indicative of some higher level bug that itself could cause a problem. Odds are this is not the case, but might as well point it out just in case. Maybe its a result of a cache somewhere from my previous install (although study session and due notes were complete before I deleted the app).

 (maybe it even has some connection to why the "Continue Session" button remains active after completeing a session, unless you go open back up the completed session and exit it once more to toggle it off).
