I've impressed by a backend theme, not free but paid, about two month ago. at, https://apps.odoo.com/apps/themes/13.0/allure_backend_theme/
but now hen I access this link (have some intention to buy it), it shows HTTP 404 error.
There is nothing about what happens about this app, just like it has never been exists...
So, just have the question, what it's the off-shell policy about odoo apps? and what if I just buy this theme app before it get off-shell?
Thanks!
