I like that it's easy enough so anyone can use without having any technical knowledge of computers or even how websites work! It has made our life easier by allowing us access into all areas we need with just one password instead of multiple logins which would be required otherwise if using other software/apps (like Google Drive).
Nothing really comes out as an issue at this time but maybe in future updates they could add more functions? Maybe some way where you don't have to open up your email everytime someone sends something important via Gmail etc.? We've been able solve many issues regarding security within different departments such as HR & Finance through its ease-of-use features when compared against others available online - also makes backups much quicker than before too :).
