Hi @thejus03 maybe following the prerequisite beta workflow, instead of a feature flag, it'd be good to have

1. a banner at the top that says the optimizer is still being tested as a beta
2. buttons on the banner to report issue on GitHub + Telegram group

this is so we can track potential launch issues better

[thejus03]

Sure! I have implemented a possible design (as seen below). Its mostly following the same notification shown in the timetable page.

On desktop

On mobile

My bad, realized it was a bit clunky. So removed the alert and made it leaner with just the buttons you implemented. Can lmk your thoughts @thejus03

[thejus03]

Looks good!

[jloh02]

Great! We will merge this once CPEx is over and pending the #4340
