Hi
I facing the issue in multiple device connectivities. Recently we have updated the local server binary to 0.28.3 also updated the latest version android APP. After this update, multiple devices are not working. I have checked local server blynk.log file and I didn’t get any error. But the same device works well in single device application.
Look like the virtual pin is having the issue. Because device status shows online when the device has power.
Note: We didn’t update the Blynk Arduino library.
