A product name is a label. It appears on tiles, in exports and in the messages we send to connected shops, and it has never had any part in producing a picture — the photo is made from the product's own photograph and the settings you choose.
Even so, a product whose name ran past 200 characters had every generation refused. The order was accepted, the credits were set aside, and each picture then failed with a message saying something had gone wrong on our side. It happened to names that were never typed as names: a description pasted into the field, or a name taken automatically from a very long file name.
The credits were always returned in full, so nothing was ever charged for a picture that did not arrive. What you lost was the time — and, worse, the thread: the message gave no hint that the name was the problem, so there was nothing to act on.
Two things change.
A name is now limited where you write it. The field stops at 200 characters and shows you how many you have used as you approach it, so a pasted description is caught while you are still looking at it rather than after an order has been placed. A name taken automatically from a file name is shortened to fit.
A name already stored no longer stops anything. Where a product's name is longer than that — because it was saved before this change — generation simply proceeds, and the label is shortened for the record it is written into. Opening such a product for editing shows the full name, so you can see what is there and shorten it yourself; saving asks you to bring it within the limit first.
Nothing about your existing product names has been altered. The names stay exactly as you entered them.
