I use this great tool every day, but have noticed in the past few days the responsiveness has been slow, and has timed-out many times. This is preventing me from using the service. I'm wondering if there are reasons for this? Please help, because if the responsiveness lag continues I may need to move onto other task management tools, most of which I consider inferior. Note that I am using the basic service, and wonder if the paid service has more focus on responsiveness? Thanks.
