How long does usually for “In processing queue” going?

Sorry man, it works by reading your previous solutions:
For all new Google Merchandise Center users , may use below useful hints to help.

1) Download and install the new update (version 1.8.3) (download from your account page here: https://www.wpmarketingrobot.com/your-account/)
2) First open the Feed Manager -> Settings page and there click on the “Clear feed process” button
3) Just to be sure, try generating a feed. This will probably not work, but because the background process does have some advantages, it’s worth a try
4) If step 3 does not work and you’re feed still stays in the processing mode, proceed with step 5
5) Again open the Feed Manager -> Settings page and click on the “Clear feed process” button
6) Then select the “Disable background processing” option
7) Try regenerating a feed again and this time it should work!

Step3: Refresh at the “Feed List” Table.
