I am utilizing react-share buttons on my website to enable sharing functionality. However, I have encountered a specific issue regarding the UTMs I use for behavior tracking on mobile when sharing content to Facebook. The UTMs seem to be appearing incomplete.

To provide some context, I am using static UTM parameters in the URL, including source, medium, and campaign. However, when the link is shared on Facebook's mobile version, only the first parameter is visible in the shared link within the Facebook profile. It's worth mentioning that this issue is exclusive to the mobile version, as the same library functions correctly on desktop computers.

I would greatly appreciate it if anyone has insights into what might be causing this issue.
