My System:
macOS Mojave Version 10.14.5
iMac (Retina 5K, 27-inch, 2017)
Processor 4.2 GHz Intel Core i7
Memory 32 GB 2400 MHz DDR4
Graphics Radeon Pro 580 8 GB
This function was working correctly in the early builds of PM+ beta, however I am unable to pinpoint the exact time the problem began because I attributed it to Flickr. Recently, I opened some of these JPGs with bad GPS data in ACDSee Photo Studio 5, reassigned the GPS location data using their map system, uploaded to Flickr and the coordinates were correct.
