Manual journey assignment limit

Hi Team,

Do you know if there is a maximum limit on the number of employees to whom a journey can be manually assigned?

Let me explain better: suppose we want to manually assign a journey to multiple people. We noticed that when entering 10 employees, the journey is assigned to only 7 out of the 10. The 3 employees who didn’t receive the journey initially do receive it correctly if assigned individually afterward.

Thanks in advance,
Vittoria
