This issue was detected, on May 8, 2024, at 12:00 PM CET. The engineering team promptly began investigating the incident at 4:07 PM CET on May 8, 2024. They worked to determine the scope of affected customers by testing various versions of the Templafy Desktop Host. By 4:38 PM CET, the team had identified and deprecated the problematic Templafy Desktop Client version to prevent further customer upgrades. By 4:52 PM CET, the incident status had moved into the mitigation phase. For customers already impacted, the team identified two solutions: reinstalling Templafy Desktop or removing the content of Templafy Desktop Client versions and restarting Templafy Desktop. These solutions were communicated to the relevant individual customers. To prevent the issue from happening again, we will fix the root cause and implement further testing between version upgrades.
