Ive had this app for months. I loved it. The longer I used it the more data I got which was great. But lately, a few times the alarm hasnt gone off causing me to be late for work. I dont know why this is happening now because it never used to before. This issue should really be fixed ASAP or they are going to lose a lot of users.
