Update Cancelled my Subcription

I was about to make a phone call when I noticed the update icon. Updated the app and my login information was erased. Re-entered my password, and everything was gone. Their customer service is exclusively email with zero English service: zero. So, it’s been impossible to get my number back since my update. Japan quality isn’t what it used to be back in the 80s.

Needs serious fixing

Use once and it freezes and needs to be reloaded. Does not stay active in the background and will not ring or receive calls.
