Can't share photos from Lightroom on Ipad to Instagram

Hi,

I've been trying to update my photography album on Instagram with photos from Lightroom on my Ipad and I'm unable to do so.  Normally, I would choose the photo, click share, choose IG, add a blurb then post.  Now its soing something weird.  A box appears and at the top there is a phot icon but no photo, then  there is a space that says search (search what) and at the bottom of the box ther eis a blue box that says "Share" and underneath that it sais which IG account I'm logged into.  I need help with this.  I'm trying to upload my photography which used to be a seamless process but now I'm not sure what to do.
