Click the Reblog button, then on the Reblog screen, right next to where it says “Reblog Link” at the top, click the little grey rectangular box that says “as…” then when two more grey rectangular boxes pop up, click the left one, which says “as text.”
Then the whole piece will show up on the Reblog screen. Then just click “Reblog post” like always! :)
Let me know if you’re not able to figure it out!
P.S. Apparently smartphones don’t have this capability, though!
