Here's the beginning of my "Crucial Tips for Using MyCanvas":
o Browser requirements are specific. When using IE 11, one must register ancestry.com and mycanvas.com in the Compatibility Settings section for MyCanvas to work properly.
o When selecting UPDATE on any given page of one's book to overwrite old information with new data from Ancestry.com, individual pages are updated....cumbersome, but necessary.
o Many pages don't allow an UPDATE, such as any page that includes a descendant. Changes need to be manually for those pages and if you're working on a 200+ book, that's lots of manual updating.
o One's computer cache needs to be emptied frequently when working with many images. Temporary file capacity needs to be increased, as well.
Hope this helps!
