I search something under the yotoicon.com and it shows the loading icon. Then nothing appears. I have tried many simple words. Nothing appears

I have done the following to try to make the icons appear when i type anything into the search:

-refresh the page

-restart browser and computer

-deleted and reinstalled the extension

-completely reset my computer to new and then reinstalled it again then refreshed

-checked permission and everything is approved

-tried different playlist

-tried different computers

-tried different google profiles

UPDATE: works rarely sometimes for 2-3 icons a day, but then goes back to loading with no results.
