iPad Dorico iconica download malfunction

using ipad chip A16 and dorico 6.1 apple pencil/fingers, very strong internet connection.

For several days I’ve been unsuccessfully attempting to download iconica sketch to my iPad Dorico version. Download goes to 60+% fails then reboots and download starts from 12% or 15% for another run of this infernal merry-go-round. I can’t leave download overnight bcs download constantly fails and I have to chaperone it back into downloading again, all for naught; when it hits 60%+ the download restarts from 12 or 15%. From other posts I see this is a recurring struggle for many.
