Digital Signature Meta-Data

Help? I review many documents daily and often shop drawings come in with the signatures on them. Usually, I just click I don't want to see the signature data and move along, but one day I accidentally clicked on the "save this choice" or however it is worded and now I can't figure out how to turn this feature back on! I can no longer validate my own team's digital signatures because I can't see if the meta-data is there😖 Does anyone know how to restore this function? Thank you
