Last year, we deployed Adobe Acrobat DC with a perpetual license key with offline exemption. Within the last week, some users, less than 5%, have been prompted to log in when starting the application rendering it unusable. The current workaround is to uninstall then reinstall the software and we're looking for a better way. What is the best way to troubleshoot this issue?
