Notes on switching from App Store billing to Sourcenext's code version for Dropbox

Here are the actual steps for switching from the iOS (AppStore) trial version of Dropbox to the Sourcenext online code version.
If you purchase the Sourcenext code version available on Rakuten, you can use the paid version quite cheaply thanks to point rewards.
I purchased the 3-year version.
Sourcenext Dropbox Plus 3-Year Online Purchase (Latest) | Compatible with Win・Mac/iOS/Android | Online Code Version
Purchasing from here would be a great encouragement!
A 6-year version is also available.
Sourcenext Dropbox Plus 3-Year x 2 Set (Latest) | Compatible with Win・Mac/iOS/Android | Online Code Version
A 9-year version is also available... but the cost-effectiveness diminishes around here as you reach the point reward limit, so I'll omit it here.
We also introduce the steps to "extend" your license using a Sourcenext license code here.

Unsubscribe from AppStore billing
First, let's unsubscribe from the AppStore subscription.
Tap "Account > Current Plan" in Dropbox.
Tap Cancel Plus Plan.
Tap Cancel Plus.
According to the description here, canceling Plus does not seem to immediately delete your data. (Please check the latest information to be sure)
The AppStore subscription will open, so tap Dropbox.
(I forgot to take a screenshot, but)
Please unsubscribe.
It will look like this once canceled.
After this, I tried to apply for a Sourcenext license key to return to the paid version, but I couldn't apply until the AppStore subscription expired.
So, let's wait until the AppStore subscription expires.
Sourcenext code version in advance.
Apply for a license key after the expiration date
The AppStore subscription has expired.
Now, let's apply for the Sourcenext license key.
Use the "Subkey" listed in the email from Sourcenext.
Please have it ready in advance.
The subkey format is xxxxx-xxxxx-xxxxx-xxxxx-xxxxx.
The purpose of the main key is unknown.
It displayed "Dropbox storage is full." The plan has also reverted to Basic.
Tap here to proceed with the license key application.
The browser has launched.
Tap "Upgrade" from the icon in the top right.
Tap "Apply for license key".
Enter the subkey listed in the email, set the country to "Japan", and tap "Start using Dropbox Plus".
It now says "License key applied".
The app has also reverted to the paid version.
That concludes the notes on switching Dropbox from AppStore billing to the Sourcenext code version.
I was a bit worried because it was necessary to let the paid version's subscription expire once, so I decided to write this article.
I hope this helps someone.
