Lightroom to Instagram process

Hi,

I’m interested in honing my Lightroom to Instagram process to hopefully make it quicker and more importantly to post in the best quality.

I‘d love to hear other peoples processes and tips.

I process mainly in Lightroom mobile

Then send at max to Mix for resizing and adding a watermark which is stored in creative cloud.

I then save it back to Lightroom at full so I can then add it to my camera roll at 2048x to hopefully avoid compression.

Sending straight to to Instagram via Lightroom doesn’t work very well for me especially for multiple images.

I’d love to hear any quicker or better quality routes!
