RD Client for iOS/iPadOS - Speech to Text doesn't work

Question

Hello, not sure if anyone here has had any issues with iOS/iPadOS native Speech to Text no longer working with the RD client app. This used to work, but as of a few months ago has not worked anymore. I'm not sure if this is something Apple broke or if it's the RD client that's the issue, but it's very frustrating for employees at the company I work at that dictate notes since they haven't been able to do that anymore.

It'll come up with the microphone icon after pressing the dictate button on the keyboard and then shake like you didn't talk or it didn't hear you.

I've seen various forums suggesting to set the keyboard to English (Canada) in iOS instead of US, but that didn't help for us. Posting here since it was a feature that used to work with the RD Client, but no longer does.
