not able to upload file using field service mobile app

i'm able to upload file for only first record of service appointment from mobile app . but not able to upload  file for current record id using field service mobile app. i already created a currentid and recordid variable and it's working fine for desktop but not for mobile app. it doesn't give current record id.

Thanks in Advance .
