@dovesong Totally agree with all of this. The "when they start doing this, distract them with training" is key, as is having them listen to a "wait" command and then telling them to go get a toy so you can play.
They're such active and velco-y little guys, can't blame them for thinking theyre more important than phone scrolling
Something that has really been helpful for us is "playing" sit on the dog. Super duper helpful. You'll find the best way for you two to play, but what I do is put on his euro lead, get his bed and put it at the foot of my office chair, and then sit down in my chair with the leash around my waist. Then I work at my desk. He'll sit or lay down. And he'll stay down until I tell him to get up. If he tries to get up before then or he starts bugging me, I'll use the leash to apply gentle pressure towards the ceiling to get him to sit. And he gets bored, and lays down.
With all this being said- First take them out to potty, then make sure they have water, and that you didn't forget a meal time, and that they've gotten a good deal of activity and play already. Then choose one of the aforementioned options. But if you arent already playing it, sit on the dog is a really good skill to master
