Two short weeks after being acquired by Amazon, ComiXology has announced that it’ll be retiring its app, instead releasing a new, read-only version that forces customers to buy comic books through a website instead. On iOS, purchases are now gone, and the app asks you to visit the company website to purchase comics, but on Android, the company has simply removed Google Play payments and has added Paypal/Credit Card purchasing instead. The move is similar to how Amazon handles purchasing in its Kindle app — presumably to avoid both Apple and Google’s fees on purchases — but is likely to be upsetting to many customers, since it’s significantly less convenient. ComiXology says that all users should back up their purchases using their ComiXology account and then download the new read-only app and restore them to continue using them.
