When I try to connect my mobile phone to my laptop via the app "my smartphone", this appears on my mobile phone
But I can't find the Send Notification option because this always happens on my laptop:
The QR code is nicely scanned, both devices are registered with the same account
Can someone help me?
I recommend AirDroid as an alternative. To do this, first install the AirDroid app on the smartphone and log in there with your Google account.
Then you call up this page on your laptop: https://web.airdroid.com/# Then log in with your Google account or scan the QR code. Then the connection is established and you can then exchange data between the laptop and smartphone.
That works most reliably.
