Since Adobe apparently, since 2018, at least, have not managed to make debit card payments standard (even though it's 2021 and most people don't even own credit cards), here's a suggestion:
Offer purchases of Adobe Creative Cloud packages through the Adobe Creative Cloud app! Tada! Payment method: Google Play. Already exists! I know Adobe Employees sees these forums. So please, please kick it up the chain.
I have used Lightroom CC Mobile for a few years now, and I just cancelled it in order to upgrade to the "Creative Cloud Photography plan with 1TB" package, as I cannot do what I want with the downgraded Lightroom CC, and need access to Lightroom Classic instead.
But did it work? No. I had to waste about an hour trying to purchase, before finding out there was no single way for me to pay for a subscription.. I was first trying on phone, but I kept reaching the same agent that hang up as soon as I tried saying my email address (FIVE TIMES!). So I then tried contacting Adobe via chat, where the agent totally ignored my first message (apparently) about getting an error message about having incorrect payment information. She just sent sent me a quote right away (presented as the solution). A quote that I in the end could not use. I spent time on trying the quote link, because I assumed she read my message and the link was a workaround to the error.. before eventually being told that only Credit Card is accepted in Greece.
Now I have to reconsider Adobe, that I have used since 1999 (before the purchase of Macromedia). All because they are seemingly the only company in the world in 2021 that cannot accept a subscription on a debit card.. or that have not found workarounds for deals they already have, like charging through portals like Google Play where they obviously already have the possibility to charge me a subscription.
Going back to just using Lightroom Mobile when I cancelled it and set my mind on Lightroom Classic? Nah. Reply to this when you fixed the payment methods, and I might come back. Unless I have already gotten acustomed to or locked my self into a subscription with your (now very potent) competiton.
