BLE connectivity issue

I have used the app a lot for my projects. I have always used HM-10 Bluetooth module to connect to the app via Bluetooth (BLE) and it always worked until yesterday. I have thus come to know that there is issue some issue with the app since it is the first time I tried the app since the recent update. Kindly fix the issue as soon as possible as a lot of things depend on it. Thanks!

Super app

Fantastic app. I log a lot of Home information to my phone. I can even monitor the location of my car with the app. Superchart has high resolution mode, which was standard first. Superchart is super cool and convenient way to chart data. Looks beautiful.
Tech support and forums very helpful. I interface raspberry pi, esp8266 and particle photon data to the app.

A full 5 Star app

Great App

I have tried many IoT services/platforms. NONE of them are as good and feature rich as Blynk. They also are very supportive and highly active in the community discussions. They are real coders. We know what motivates us, and they are no different.
