Problems with push notifications in the Blynk App

Hi guys, I was using my old blynk app until a few days ago without any problem … I know I have to migrate to the new blynk 2.0, I want to know if the same thing is happening to someone … my team is basically a communicator of events of a home alarm … it has to notify by means of push notifications some changes in the system, until recently it worked perfect, but now it only works well with my nokia cell phone with android, with other cell phone brands when the cell phone is locked With its screen off, notifications are not entered, when opening the blynk app all push notifications are automatically entered, on the other hand if the cell phone is with the application open or in the background when it is locked if they enter … all very strange and unsafe . thanks in advance guys!

Obvious before writing this check all the configurations of the cell phones that present in problem. and all the settings were with priority for blynk, everything perfect there

What version of the Blynk library are you using?

Pete.

Hi Pete today update to the latest version, which is in the Arduino ide manager, since I did not have the latest version installed, and I still have the same problem.

And you’re using the new Blynk IOT app?

no, I was testing and I can’t get it to work! since my code uses notifications a lot, and with Blynk 2.0 that changed a lot. I also understand that I can continue using the old Blynk for a while longer …

What’s the problem?

Blynk keeps the old server up, but it’s not known for how long exactly…

If you want to keep Legacy (old Blynk) you’ll need to use library 0.61.

Hello, I migrated all my code to blynk 2.0 and I still have the same problems, I clarify that in those cell phones it always works with the Blynk notifications but not now.

When using blynk iot you should replace blynk.notify with blynk.logevent.
