ACR disables itself

Im using Automatic call recorder
it records all the incoming and outgoing calls on my phone
the thing is after a while, on a random bases, i find it disabled!
what happens is when i actually need to pull a record of a call , it didnt record it cause it was disabled, make the app completely useless
obviously i enable it back on , but somewhere down the line, in a day or a few hours it gets disabled again.

Android 5.1.1. Update Disables Mobile Data (D5803)

Hello,

I recently updated my Z3 compact (D5803) to android 5.1.1. on the T-Mobile network here in NYC. Ever since then, I frequently lose the ability to do anything data-based with the phone. No web browing, no chatting on whatsapp. I can still make phone calls and send/receive SMS, however. The data functionality returns when on WiFi, but goes away once I switch back to LTE. In order for me to get data on LTE, I have to manually download the internet settings for my provider to my phone (this is located under the Settings menu in android). Even then, it only lasts for several minutes before the data connection is lost. T-Mobile was unable to fix the problem, and changing the SIM card didn't resolve the issue.

Anyone else experience this?
