I have been using 500px quite extensively in the past, but I haven't used it in the recent years. I used to be able to export to 500px directly from Lightroom classic, but things seem to have changed: On the 500px support page it says that the export plugin has been discontinued.
Now I wonder why that is? That plugin made people use 500px, why would they cut off their customers from their development flow?
And more importantly, is there any alternative plugin that I could use for that purpose? Google did not spit out anything really useful?
