For users that have made a purchase, add a link to Managing purchases, renewals, and cancelations the suggested InlineHelp links on the following pages:

• plans
• my plan
• settings
• support
• customer home
• any purchase-related screens

PR for this issue in #45408. :)

It's hard to tell from the description, but I think these are the routes that this is referring to. Please correct me if I'm wrong.

• /plans/:siteId
• /plans/my-plan/:siteId
• /settings/:siteId
• /help (I can't find anything else that I would think of as "support")
• /home/:siteId
• /me/purchases/:siteId/:receiptId (a "purchase related screen", I guess)

My Home (/home) doesn't appear to include the Inline Help button, so I just excluded it from the PR. Let me know if that should change. :)

@fditrapani can you confirm that the above routes are the ones you were referring to?

[fditrapani]

Thanks for pulling that list together @sirbrillig. Those are correct, in addition to that, I would also include:

• /me/purchases, and
• /domains/manage/:siteid
• /domains/manage
