Lettercase transforms no longer working

I love the Text > Text Uppercase / Lowercase function in Figma, I used it profusely until about a month or two ago when it stopped working for me. Several updates and reboots later, it still won’t come back. All the other text transform options (e.g. bold, strikethrough, increase/decrease text size) work for me except the Text Uppercase / Lowercase / Original Case. Other members of my team have tested and they still have the full functionality. Is this a permissions thing? I miss my letter case transforms so much, I hope someone has some idea of how to get it back.

It sounds like a bug, you need to report it to Figma support team via support@figma.com or the support request form.
