The whole app is amazing and the design is flowless, i am really amazed of the UI/UX, although, the mobile mode view has some flaws as the previous version was great but this latest update need some few adjustments as the menu is hidden, I have added bootstrap class "vh-100" in MobileNav.js after mobile-nav-menu it solved the problem, and it had some other issues like the calendar.
I hope you find this feedback useful to enhance some of the mentioned flaws
