Hello,
Yes, unfortunately there will be no Face-to-Face Developers Conference this year, and your guess is as good as anyone else's when the next one will be held. But late 2022 seems reasonable.
On the other hand, there are plans to maybe have a Virtual Developers Conference online already this year. I don't know more than that, but there is a high demand, from customers and Danfoss, to arrange this. More information will come.
In the meantime, you are more than welcome to give us tips and ideas on what topics you may be interested in. Both for the Face-to-Face and the Virtual one.
Have a nice day.
