This isn’t a big deal, but it started so suddenly I thought I should let you guys know.
I have a number of components whose dimensions depend on dynamic formulas. A few hours ago, the Previewer started showing them with the dimensions wrong after I saved in Composer and the Previewer refreshed. Wanted to give you a heads up in case it’s indicative of something more significant. For now, I just re-open the app in the previewer and the dimensions are all back to normal, so not a big deal.
