'Refresh Preview' gone from Home Menu Bar in Aug 2025 update when using Dark Mode

In the latest update (2.146.1133.0 64-bit (August 2025)) there has been changes to the option bar in the 'Transform Data'/Power Query screen, particularly in the Home bar

Couple of things ive noticed - 'Advanced Editor' has moved to View

However 'Refresh Preview' has disappeared,

This appears to be a bug - relating to Custom Appearance - as there is a workaround in a reddit post https://www.reddit.com/r/PowerBI/comments/1n0brm9/where_did_power_querys_manual_refresh_preview/
(thanks MasonMA)

- Switch to 'Legacy' (in File - 'Options & Settings' - 'Options' - 'Global : Report Settings')

- I also needed to close down Transform Data (Use the X button and Dont apply if youre still making changes)
- then reopen 'Transform Data' and 'Refresh' reappeared
