Linking two tasks in two different milestones

I have created two milestone m1 and m2 also two tasks t1 and t2. tasks t1 is link to m1 and t2 is linked to m2. There is a dependency between these two milestones so i need to create a link between t2 and t1. I could not do it via onlyoffice project module(workspace- version 12.1)
is it possible to do this ?

Hello @vs30217
Please record a video file of your actions. There’s a way to create dependencies between tasks: Managing your project using the Gantt chart
But it’s not clear what exactly goes wrong in your scenario so far.
One more thing, please update your installation to v.12.7. The v.12.1 is outdated.

Hi @Alexander_Onlyoffice I have updated groups to latest version 12.7, however i am still not able to link two tasks across 2 milestones. I am attaching a screen recording for 2 milestones m1 and m2 having tasks, t5,t7,t1 and t6,t4 respectively. I can link tasks within a milestone but not between milestones.

i have attached the shared link of screen recording for your reference.
