Multiple photos form Flickr-App to Instagram

Hi folks,

I don't know if this is an appropriate place to post this question, as it isn't necessarily directly related to posting photos on the forum but it is quite urgent and I feel it might be relevant for some of you.

The problem is that I can't figure out how to post multiple photos from the Flickr-app to Instagram (on my phone obviously).
I am able to click and view a single picture in Flickr after wich the share-icon appears. Clicking it brings up a list of apps I can share to including instagram feed and stories. However when I select multiple photos on my cameraroll or in an album and click the share icon that pops up after the pictures are selected the list of apps that appears only mentions Instagram direct which brings me to the instagram chat page wanting me to send the photos to someone on instagram instead of uploading them there.

So the question is, is it possible to post multiple photos from the Flickr-app to Instagram at once?

 

Uuugh, I was afraid that this would be the case -.-
I thought I finally found a good way to get high quality pictures on Instagram but I don't want to spam people with numerous single posts.
Guess I'm using your method instead, thank you^^
