The official website for the Yuri!!! on Ice: Ice Adolescence movie streamed a teaser trailer for the film on Thursday. The team had previously shown the video at an anime in January 2019, but had not released it online until now.
The Twitter account also posted a statement regarding the production's progress, stating that it is still ongoing with the goal of enriching the production; however, the team stated that they are not yet able to provide a release date.
The team announced in September 2019 that they would be postponing the premiere of the Yuri!!! On Ice movie. The announcement at the time indicated that the postponement was in order to substantially increase the content beyond what was originally planned.
