This condition will check in your recent LinkedIn connections if the current lead accepted your request:
If after "7" days, the lead hasn't accepted your invite, the next action (Like post here) will be performed :
Note: Be careful to set the same number of days between a "When Accept Request" condition and an "Invite Not Accepted" condition.
Otherwise, you risk losing leads!
Example: If you set During 7 days and If after 10 days, if a lead accepts your invitation on day 8 he won't continue the sequence because he doesn't validate either of the two conditions!
