How to recover your WA credits if you lost them without receiving site feedback
Not quite as represented by the cover image although that usually helps as the last resort. Before throwing toys, if you submitted feedback request for your website ages ago via the Site Feedback platform and never got any reviews (it happened to me), here is how you can recover your credits (in case you haven't already and no longer need responses):
There is an "actions" button located on the right side next to your request, tap the drop down icon and cancel your request. As shown below:
It might take a few seconds to retain your credits, but if it takes unreasonably longer, you can then escalate the matter to Site Support.
I hope this helps someone
May you all have a productive week :)
