There used to be a 'New..' button when selecting which album to export photos to Google Picasaweb / Photos. Where is it? As it is I can only upload to existing Google Photo albums. The only way to create a New album on Google Photos (on the web) is select existing uploaded photos and create a new album. I don't think I can even create a new empty album for Digikam to upload to.
Thank you to Google. This bug is a duplicate. All information in the first bug report. Maik
