How to fix my Twitter app for iPhone?

Just signed up a week or so ago & I used to get an alert sounding off when my app had a notification, as well as the usual little red circle "badge". Now neither one rarely appears/sounds off. I don't know why but it would be nice to know how to fix this issue. All my settings are set to alert me when I get notifications but it just doesn't happen.

Why can't I do facetime now on my Iphone 4?

It used to work when I called my daughter who lives 240 miles away. She still lives in the same place with the same cell phone number. Why would it not ever connect now.

My iPhone Garageband files that I stored in iCloud have vanished. Has this happened to anyone else?

I have an iPhone 5c. Since I upgraded to iOS 8, I haven't been able to find the Garageband files I uploaded to iCloud. This was the case before and after I converted to iCloud Drive. According to Apple's info on iCloud Drive, I should have no problem accessing the files if I'm using an iOS 8 device (I'm not trying to access them with my computer, just my iPhone). I've seen other people posting about problems with Garageband files in the cloud, but most of them can actually see the files in the cloud and are having problems with functionality. I can't find any trace of my song. I'm certain that I uploaded it, I just don't know where it is now. I deleted it from my device once to free up space, but again, I deleted it from my device, NOT the iCloud. Just wondering if anyone else is having problems with files being deleted from iCloud, and if you have come across a solution.

Is he faking his whatsapp status?

I think the guy I'm dating is faking his whatsapp data. Today he sent me a message at 17.45 but his last seen says he hasn't been online since 15.15. Is it likely that there's a glitch with whatsapp? Or is he faking his status somehow?
This is the first time he has sent me a message while "offline", but I have noticed before that my messages to him often only have one tick for a long time. I could be wrong, but I don't think he turns his phone off while at work. What else could be causing this?
I did try googling to see how easy it is to fake whatsapp data. I don't think he has watusi because he has an android phone, not iphone. But is it possible to edit data on an android whatsapp?

For the record, although it may sound like it, I'm not texting him 100 times per day, just once every few days. But is he lying to me about his replies?
