OK, I tried to do an instruction in this thread, I created a new ticket to ask a support. Then, I can see my old tickets.
However, when I clicked on one of these 2 tickets to read, it automatically went to a new page.
It means that I cannot read my all tickets.
I try to open them on my computer as well as my smartphone, but it’s useless.
How can I do now? I cannot contact Fiverr support.
