My mobile subscription has expired, but Dropbox still won't let me re-subscribe via the website

Hello. I am trying to switch my subscription from Apple mobile payment to the Dropbox website. I have already followed the instructions provided by Dropbox and cancelled my subscription with Apple. According to Apple, my mobile subscription expired on August 7th (10 days ago). However, when I go to manage my subscription on Dropbox.com, I am told I have to manage my subscription through Apple and not given the option to subscribe via web.

To make matters more frustrating, when I try to contact support by email through Dropbox's website, I'm given the same set of instructions I already followed and not allowed to submit a support request. I haven't attempted to use the live chat because it's not available on weekends, and if I'm going to have to wait until Monday to receive support anyway, I'd rather be able to submit a support request now while I'm thinking about it and handle it asynchronously than have to remember to do it on Monday.

It's incredibly frustrating, and from looking at the forums, it seems like this is a problem multiple people have had that has required email support from Dropbox to resolve.

I would primarily like help resolving this issue so I can subscribe to Dropbox via the website.

However, I would also like Dropbox to consider updating the "Submit a Help Request" form to allow people having this issue to, ya know, use it. The fact that multiple people have posted on this forum about this exact same issue shows that the instructions provided are insufficient, and genuinely the most aggravating part of this entire thing has been being stonewalled by Dropbox's support request UI.

Please either update the instructions with troubleshooting steps when your subscription has expired on mobile but you're still unable to change your subscription plan on the website, or, if this always requires Dropbox support to resolve, provide a way for people in this situation to indicate as such in the "Submit a Help Request" form that will allow them to, ya know, submit a help request.
