Contractions: good or not?

Hi!

I've recently discussed using contractions in technical writing, mainly for
user interfaces.

There's science that supports increased readability when contractions are
used: https://twitter.com/FriendlyAshley/status/1450180256694951945

Is there anything pointing to the opposite?

Most technical-writing style guides say contractions should be used,
especially when writing in a friendly voice.

Modern screen-reading software must surely have no problems with
contractions?

Please let me know if there is any science out there that says contraction
shouldn't be used for accessibility purposes.

Thank you!

Best regards,
Niklas
