Allow ability to add color transparency to images and shapes.
You can’t change the transparency on images or shapes in PowerPoint on iOS. This is a shame as it renders the iPad useless as a device for work.
For now you will just have to make a pptx on the computer with a transparent object and from the app you can modify the colors and shapes. (The opacity is maintained)
Copy and paste it to future projects. Hopefully it’s only a temporary workaround.
