Oh if we only had $ for each time this came up, we could buy out Blynk (original) and keep up with end user, hobbyist and DIYer use and development.
@Redhuan I highly recommend you read the (Blynk original) documentation while it is still available. Your code is trying to do too-much-too-fast by running (or calling⦠same thing) all your functions in the void loop()
What sometimes works on the basic MCU boards (or emulators) and āstandardā Arduino style programming, will not work once you try to add in the timing and processing needed for IoT communication and interfacing.
Look at the Keep your void loop() clean article firstā¦

And delays are BAD with Blynk and other timing critical stuff. Look into how timers work.
