Hello, dears,
After adding 5 more users, my plan is up to 10 and I had 3 including myself, so in total, we are 8 now, User Management stopped working, it is not giving any error, just opening a blank screen after some loading.
After some more time, it shows the attached screen (screen 1)
And inside the network tab, I can 504 error attached as well (screen 2)
