Hi @dayna thanks for posting in the community! It looks like you may have infinite canvas enabled for your document which is why "Zoom to page" is not appearing in the view menu. 

To disable infinite canvas please open your page settings from File > Page Settings > Canvas > Infinite Canvas and toggle it off. 

After the above step you should be able to see the "Zoom to page" option in the view menu. Could you please give this a try and let me know if you see any improvements? 

I hope this helps. Feel free to let me know if you have any questions!
