Minor thing: I used the three-dots on the main project screen to clear intermediate results for two projects. In both cases, I received two notifications: one that said the results had already been cleared, and another that showed a progress bar saying the results are being cleared. I was only able to snapshot the last example, but in both cases it happened. The P3 clearing finished notification disappeared after a few seconds.
Thank you for reporting this issue. We will take a look into this duplicate notification behaviour and make a fix in an upcoming release
