I want to add a summary formula to a lightning report. But when I click the '+ Create Formula' link in the field list on the left, nothing happens. No formula creation popup window.
I can create formulas in classic, and in lightning I can edit formulas that I have created in classic - the formula editor window pops up just fine.
Previously, I just chose 'Edit in Classic' to create formulas. But in this report I have used the new Show Unique Content feature on a field, so the report is now Lightning only and cannot be edited in Classic at all.
I'm stuck! Anyone know how I can create a formula in Lightning?
I'm using Chrome on Windows and my site settings allow popups.
The fact that it's intermittent leads me to suspect that it's browser related
