Places/Parking Lot

As the new Parking features are being rolled out, PLAs are being imported to the map by Waze. This guidance should be used to fix up those imported PLAs. However while we wait for additional features to be released, currently any PLA will be displayed as a visible area on the client map creating clutter. Current guidance is therefore not to add any new PLAs until the client is updated (soon™) to not display PLAs. Places/Parking Lot
