Devices not visible to users in PLUS Plan...sorry everyone I am not good with forums

I don’t have any issue with my code it works fine, it has been working for a year or more but suddenly last week all my users logged out and now no-one can see my device.
I tried to delete and re-invite the users but still no luck.
They’re getting a message saying “YOU HAVE NO ACTIVE DEVICE”.

@AteeBull Please edit your post, using the pencil icon at the bottom, and add triple backticks at the beginning and end of your code so that it displays correctly.
Triple backticks look like this:

Copy and paste these if you can’t find the correct symbol on your keyboard.

But, TBH, your code is irrelevant in this situation. You should be providing I formation about who owns the devices within Blynk.


Thanks for the reply Pete…
I honestly have no idea what you asking me to provide…
Issue is very simple… Even the heading of the topic is self-explanatory… all I am asking if Blynk has changed anything which is causing this issue suddenly…
I owe the device it’s in my house and I have 2 users who had access to this device… it’s for our automated gate.

I’m asking about which user owns the device…


Admin owns the device like always…Nothing changed in the code or settings

Does that mean you?

The more info you can provide the better!


Thanks for the reply Pete :pray: yes I am the admin and I have my wife and my daughter who were using the app to control the gate.
Initially I shared the device by inviting them both, and it was working fine but there are getting message on there phones saying ‘You have No Active Device’

With the new Plus permissions I think you’ll need to have your wife and daughter sharing a login, and transferring the device ownership to that login.


Thanks Pete
So Blynk has changed something without any notice,
I was going crazy why everyone loged out and I couldn’t fix it.

So that means 10 Devices and 10 Users, now 10 Devices and unlimited users??? Because whoever has the login can access that device…is that right :+1:.
Do I have the right understanding Pete?

Hi there,

Only owners of device can see them. You, as admin can see all devices.

Blynk actually communicated this change.
