From the website: "Service Note: Instagram has updated their protocol and currently plugin does not work.With the LR/Instagram plugin LR/Instagram - Lightroom Publish Plugin for Instagram
Some people do mention problems with it but i'm using it without issues on the latest LrC and Windows 10
I gather you are using it in spite of the warning. In that case I'll give it a try. Thanks for the tip.From the website: "Service Note: Instagram has updated their protocol and currently plugin does not work.
We are investigating the issue and the plugin will be updated when a fix is available. "
I do this too but it is a pain as it takes way too many steps. There really needs to be a reliable plug-in. The one I use for SmugMug works perfectly. I'll also point out that the option to have multiple photos in the same post is not available using this "pretend" method.I now export from LR and then use my web browser, Chrome, switching it into Developer Tools mode and pretending to be an iPhone.
