Good idea, but many issues and needed updates

The app wont allow me to login, but I can access it on the mobile website (looks and functions the same)??? I like the app when I am able to use it... I own a few properties that I lease, so I use the app somewhat often. This app has worked fine in the past, but it could use many upgrades and needs some of the bugs fixed... It tells me my email address is not valid, but when I receive an email notification it is sent to the same email address that I try to login with. Also when I use the mobile site, it shows my email address correctly in the settings. Ive also found that I can open an email notification then click on the listings button (orange button) and it will open the app and function properly until I stop using the app for a few minutes, then it wont allow me to login again... Fix this please.
