Cannot perform administrative functions on the App on my iPhone

Any time I try to use the App to perform administrative functions (attendance, create calendar events, send an email, etc.), they do not save/work.

I have at times had this happen as well. Just the other night I went to send a text from the app and crossed my fingers, in this case it did send. Unfortunately at this point I have really resorted to using the App for quick lookups and info but rely on the browser either phone if really necessary or computer to do all of my major updates.
