@MetaGrid_Admin this explanation sheds light on the same issue I reported earlier (MetaGridPro is Consuming Huge Data).
Even without custom images, my setup for applications such as RX, DaVinci Resolve, Studio One/Pro, WaveLab, and SpectraLayers requires 12+ grids per app, which appears to push data usage beyond 40GB.
Reinstallation is currently the only way I’ve found to reset it.
