After I fill in new credit card fields on the Acumatica website and then click “Save card” button, nothing happens.
I spent a whole day with Acumatica support trying to figure out what the problem is.
I tried browsers Chrome, Edge and Opera. Then I installed Firefox, and Kaspersky Password Manager starts raising a series of dialogs asking me to save info into it. I uninstalled PM and rebooted Windows. After that, everything was fine.
