So, I submitted a shop but realized I incorrectly submitted an answer. I Notified the MSP guy and he said to go back to ISS and edit; there is no Edit button in the app. Anyone else have this issue?

In the app, if you go under "Assigned Shops" and toggle to "Submitted" you should be able to see your shop. Next to it, there should be a yellow and blue button that says, "Un-Finalize." If you click that you should be able to go back into the shop, make your edits, and re-submit it.

On my app, in the assigned shop, it only shows "In Review" and it's not clickable. I contacted the MSP and told him of my error and he said to email to him the photo that I forgot to include in the shop. It's still under review.

Oh, that's frustrating. At least the MSP is aware of the problem and working with you.
