Unsent data message

Hi
I am busy making a new project and has published it a few times as i am changing things.
On the phone, i see the project, with the ‘circely arrows’. When i tap on it, i see the ‘Update project’ screen and tap on ‘Yes, update now’. Here i get the ‘Unsent data’ message.
I have no projects that i have not saved and gone out of.
Regards

If there is nothing to sent, delete the project on device and install your last version again.

Thx, I’ll keep that option open.
Regards
