SOOO MANY GLITCHES ON IPHONE!!

I feel like the app on my iPhone has been so awful lately. I've had to delete it and redownload it just to be able to log in at times, and I am experiencing so many issues with test taking:

*Not being able to upload tests-- "Keep your app open while your survey is uploading" (and me waiting like 30 minutes so that I don't lose 20 minutes of test taking before just quitting)

*Screens that just never open during a test-- either a blank white screen or even now a dark grey screen that won't let me move on.

*The app mid-test saying my mic is not working.

*And also there not being a way to pause tests on my iphone now?! Is anyone else experiencing this? Esp for longer tests this is quite alarming.

Love the platform-- when it works!!
