LR unable to share image to Instagram feed

[Matthews.room]

Hi there.

I've just subscribed to LR and am using the adriod app, when trying to upload to IG feed I just get thrown back and a brief message letting me know this was unable to be completed. See attached screengrab. 

Can anyone help? The only reason I signed up to LR was to easily adjust images prior to uploading to IG..

Thanks

For about 2 or 3 days now I have the same problem. I can't share my pics from my mobile Lr on my galaxy s8 to my instagram feed anymore! Pls help!
