You can still get it. First, download Qooapp. It's essentially a Japanese play store. Then just search dokkan and download it.
Also keep qooapp, since you'll need it when jp gets updates
This should take you directly to the download page:
Just makes sure you have "unknown source" turned on so that you can install it.
I don't want a video.
You have an iphone so hit the home button at the same time as the screen button and send me pics of your str units.
Then go here > https://imgbb.com/ and it will convert them into URL
