Why is touch input for PrizmDoc not working in Chrome version 70+?

Question

Why is touch input for PrizmDoc not working in Chrome version 70+?

Answer

PrizmDoc uses the Chrome Touch API to process touch input. This API was deprecated after Chrome version 70 and must be manually re-enabled in order for touch input to work in PrizmDoc.

Paste the following link into Chrome and enable the Touch API:

chrome://flags/#touch-events

This issue will also occur in the Chromium version of Microsoft Edge.

Paste the following link into Edge and enable the Touch API:

edge://flags/#touch-events
