Cannot get spell scaling to work in homebrew

I have a homebrew spell with:

• Scaling type Spell Scale
• At Higher Levels Scaling checked
• Created as a 1st level spell with Modifier of 2d8 as the damage
• Created an At Higher Levels entry
  • Tried scaling level value of both 1 and 2, neither worked
  • Tried scaling effect of both additional points and additional counts, neither worked
  • Dice roll is 1d8

Level 2 slot version still shows 2d8 as the damage.

Don't know if someone went in and tweaked it, but it suddenly started working. Didn't work for the past half hour or so since I created it, but suddenly, it started working.

It can sometimes take up to 20 minutes for changes to homebrew to "percolate" to character sheets.

Oh, okay, thanks, that's good to know.
