Hello noleo,
Thank you for contacting the Microsoft Advertising Community forum!
I understand how important it is for you to run your campaigns with no challenges. Depends on how big the feed file is, our system needs to check what has been uploaded and it might take up to 48 hours.
When you import your Google Ads Performance Max campaigns, we'll automatically match them to either smart shopping campaigns or search campaigns. This is based on whether you included a Merchant Center account during your Google Ads campaign creation. With a Merchant Center account, we'll import your Performance Max campaigns as smart shopping campaigns; and without a Merchant Center account, we'll import them as search campaigns.
Microsoft Advertising matches most of your Google Ads Performance Max campaigns items; however, there are a few differences you can review in the table below:
Choosing the appropriate import options can determine which items get imported to Microsoft Advertising for the first time, updated from a previous import, or left untouched. Below, you can review both your import goals and the options you must choose to achieve them.
Please note that an update in Google Ads is treated as deleting the previous target and adding a new target. If you select Targeting under Updates to existing items, and if the targets were updated or removed in Google Ads, then those targets will be deleted from Microsoft Advertising during the import.
I hope above information were informative. I will send you private message if you need further assistance.
Sincerely,
Dagmara | Microsoft Advertising Support | 1(800)-518-5689
