The lengths of the non-skippable ads on Instagram, currently being tested by Meta, are not confirmed to be fixed. Based on the information available, it appears that the "ad breaks" are a few seconds long. However, it is not clear if the length could change in the future, should Meta decide to make this new format official. As with any test, the company may make adjustments and modifications before implementing the feature more widely.

The new "ad breaks" on Instagram function by interrupting users' browsing sessions with unskippable ads. These ads appear in the main feed and require users to view them for a few seconds before they can continue scrolling through their feed. This new feature is currently being tested with a select group of users. When an ad break is encountered, a countdown timer is displayed, forcing viewers to watch the ad before resuming their activity. The feedback from this early testing phase has been predominantly negative, with users expressing frustration and some even stating they closed the app upon encountering an ad break.

Meta is testing a new type of advertisement on Instagram called "ad breaks." These are unskippable ads that interrupt users' browsing experience, forcing them to watch an ad for around three to five seconds before they can continue scrolling and viewing posts.
