Hey,

We need a bit more detail to be able to help effectively. What steps have you taken so far to try to fix the issue? If you could send over some screenshots, outline the steps to recreate the problem, or provide any other information, that would really help us get a clearer picture of what’s going on and what you’re dealing with.
