So, ever since Ultra Sun/Ultra Moon launched (and honestly, before that too), we've been receiving a lot of questions about the Trainer Card Maker, when it might get updated with the new additions, when are new sprites/backgrounds/whatever coming in, and all sorts of other questions.
Pokécharms, while it is a very important part of our lives, is just that - a part of which. All of us at the Pokécharms staff are fairly busy individuals, with numerous obligations both on and off the web that are unrelated to the site and are, regrettably, at a higher priority. Things have been fairly hectic for our developers in particular - and that means unfortunate delays in non-critical systems, including the TCM.
Rest assured, however, that an update is in the works - and will be released as soon as possible. We apologise that 'as soon as possible' may not be as soon as you would probably like - but that's the situation at the moment.
We would also like to ask that you refrain from repeatedly asking the entire staff about this over and over again - we are kind of like an elevator button - pressing it repeatedly will not make things go any faster.
Thank you for your cooperation.
