I am happy to share that we have fixed this bug in our latest release – 23.0.6 which is available worldwide now.
Going forward, our goal is to fix as many top User-Voice bugs as possible and as frequently as possible. Given the nature of the fixes, some of the bugs will take a longer time to fix, but we are on it.
