Issues with using Roboto Flex in Powerpoint between Windows and Mac

**Describe the bug**
When adding Roboto Flex to a Powerpoint template in Windows and then opening that template on a Mac the font looks very different. It seems to only affect normal weight. Seems to also be true with just a regular presentation, and not exclusive to templates.

**To Reproduce**
1. Create Powerpoint template in Windows
2. Set template to use Roboto Flex, normal weight and embed the font
3. Open template in Mac

**Expected behavior**
The font to look and behave the same across platforms
