Is there any way for me to restrict user logging in to multiple device using same email? I have a calculator app and I am charging companies per user and I don’t want the employees to use same email to access my app on multiple devices.
Maybe write their device info to a static column, and then compare that when they use the app. If it doesn’t match then don’t show any relevant tabs?
Ask Netflix. They seem to have figured it out (snark)
