What is the issue?

When uploading a bulk sheet to update some URLs with the {ifmobile} {ifnotmobile} parameters, you may sometimes encounter the following error message:
 

What causes the issue?

This problem most commonly occurs in either of these situations:
 

• When the parameters already appended to the URL in the brackets in the bulk sheet.
   
• You have a query string such as question mark "?" or ampersand "&" inside the {ifmobile} or {ifnotmobile} tags.
  
  For example: http://{ifmobile:m.example.com/?subcategory=123}{ifnotmobile:www.example.com/}
  
  In this case, you need to remove "?" and reformat the URL without any query string such as below:
  
  http://{ifmobile:m.}{ifnotmobile:www.}example.com/?{ifmobile:subcategory=123}

How to fix the issue

This is expected behavior, and as such does not require a fix. If the above is not the case or you have more questions, please contact our Support Services team, who will be happy to help investigate.

Additional information  

• Google accepts ? inside {ifmobile} or {ifnotmobile} so it is possible to see this scenario in a Google URL. More information can be found here. Marin will not traffic the URL, so you will need to manually build URLs (without the use of URL Builder).
   

• Microsoft does not allow ? inside {ifmobile} or {ifnotmobile}
