Stretch Between Guides

[Cassidy5ED2]

Hello,

I am following one of the official Adobe Animate tutorials on youtube, but I am stuck at a certain point. How do I get there to be two red guidelines as shown in the second image? I can only get one to appear. Thank you in advance!

 just drag from the (vert) ruler.

Is the vert ruler that red guide line? When I drag it a second line does not appear. Thank you!

no.

right click your stage > show rulers, if they're not visible now.

Try to change the End value to see if the guide will appear:

It may be just another Mac-specific bug.

You can try to set your display scaling to 100% and restart the computer. This may or may not help.
