Hi Shivam, So far it's happening on Samsung Galaxy Tab E Model SM-T377P Software version T377PVPU3CQ14 hardware T377P.02 Android 7.1.1 which has all the latest updates. The Adobe acrobat version is 18.5.1.8310. Apparently the signatures disappear after a few days. For this reason I'm not sure if it happens across documents. The PDF that we are concerned with is a monthly log. The log has fillable fields and a space to capture signatures to document monthly overlaps. For some reason the latest Adobe doesn't automatically open PDFs downloaded to the device, which may be relevant. Only when navigating to the GDrive does the PDF open in Adobe. But that is the case for a variety of PDFs, not just the log. Please advice, or let us uninstall the latest update and return to the older version that worked efficiently for opening and editing. Thanks, TMA
