Why is the Verizon Cloud app generating Instabug text files in my File Manager Documents folder every time I start up my phone?
Well, it appears that the culprit app is the VERIZON CLOUD APP.

I went to the Instabug website. I was thinking of actually sending them a message because the path shows their software name. But, I found this article. It appears that Verizon uses Instabug, and the person interviewed for the article is Mohammad Hariri, DMTS for Verizon’s Communications and Cloud division. So, I thought I would try disabling the Verizon Cloud and and IT WORKED!!! I have turned my phone on and off three times. I don't get the text files!

So, now the question is: How can someone in charge of that Verizon Cloud app look at this issue? 

Extra: I reinstalled the Verizon Cloud and instantly got a text message in that Documents folder.
