After an edit with the adjustment brush in Lightroom Classic, there is no longer a gray circle indicating the location where the adjustment was made. This means I can't get back to that adjustment to change it, if needed. I still have the gray circle/location indicator with the radial filter and graduated filter. Rebooting didn't solve the problem. Any help is appreciated.
You may have the option to "Show Edit Pins" set to "Never" on the toolbar when using the Adjustment Brush (press "T" to reveal the toolbar if it's not showing). Change the setting to "Auto" or "Always" to reveal the edit pins. Or press "H" which toggles between "Auto" and "Never".
Thanks, Jim. That solved my problem. I had not noticed the Show Edit Pins verbiage previously. Perhaps I inadvertently changed it when meaning to click on the Show Selected Mask Overlay box. Thanks, again. John
