Archer voice has changed in Rise 360

From around 4pm UK time yesterday I noticed that the standard Archer voice has changed its tone and I wondered if it is effecting anyone else or just me. We are building content in Rise 360 and are using the AI voice generator to create narration in certain blocks. We always use the following voice, but yesterday it seemed to change and I don't know why.

Archer - Conversational Male | Middle-aged | Dialogue | Fine-tuned for conversation...

As a workaround to try retain the same voice I am having to create the narration using the same voice in Storyline 360, raise the volume by 50% to match Rise 360, export as an audio file, and then import into Rise 360.

Is this issue affecting anyone else, and does anyone know how to resolve it please?
