Cant open downloaded decks

I downloaded anki for iphone…and i downloaded anki v9 for step 1 usmle but it wont open with anki app…can i know what s wrong? How to solve this problem
I tried downloading the decks many times and everytime it failed

Anki app? for iphone is AnkiMobile

if that isn’t the case, try download the deck on the desktop version (Anki) and sync into ankimobile or AnkiWeb (browser version - free)

Please follow the steps on Shared Decks - AnkiMobile Manual. If you get stuck, please let us know how it differs from what is written there.

Alternatively, you may find it easier to import in the computer version and then sync your changes over, as NameLessGO has suggested.

Yes ankimobile… i tried synchronizing also but still the pictures or facts attached to the answer card dont open, only the answer line appears!
