Note: The following instructions are only temporary. Thanks in advance for your patience.
As of now, inserting a Logo on your slides has to be done through a manual request. We're working to implement the Logo features soon again and we'll add it for you in the meantime.
Just send a quick message to firstname.lastname@example.org sending your logo file and your presentation URL. On the subject just write "Add logo". We'll generate a custom Theme with your logo on it, for you to choose it.
Again, this is only temporary and we appreciate your patience. Bare with us as we make Logo functionalities available to you soon again.
