So what I usually do is talk to the support and let them know that I made a withdrawal. And usually they will reply to you and confirming that the withdrawal has been processed and it used be in our wallet.
Since they have already been informed about how withdrawals work at Spinly, I think the signature campaign participants should no longer have any doubt about it. Since they handle bonus-related withdrawals manually, they probably check the manual withdrawal queue once a day, though it may take longer. So, it is a good idea to reach out to the team via support and get help. I think you are doing the right thing

Anyone knows how can I access information about pending withdrawal requests on the website?
I submitted withdrawal request yesterday and have not received funds yet, so I just wanted to check if everything was ok...
Even if they handle the withdrawal manually, waiting for the withdrawal for a day is not a good thing. If you make a withdrawal request today and see your withdrawal is still pending after a day, I am sure anyone would be disappointed.
