We apologise for the issue you are facing. We are however not able to reproduce it.
Can you please try the following steps and let us know your results:
1. On Desktop, sign out from Reader/Acrobat
2. On Mobile, sign in with your Adobe id, create a signature/initials and wait for sometime (for signature to sync). Try to sign a simple PDF document
3. On Desktop, launch Reader/Acrobat, sign in now, open a PDF and go to Fill &Sign app. Open a simple PDF and try to add signature/initials now. Do you still not see the signature created on mobile? Please let us know
