I use IE Or Microsoft Edge as my PC browser, and I made sure that the TLS 1.2 is checked in the Advanced Settings menu, but I am still unable to check out of the MP. I get an error page that says "Hmm, we aren't able to find this page." I even reset the settings to default and restarted the computer, but still can't use the MP cashier. I was able to use it as recently as this morning, before the change to TLS 1.2 took place. TLS 1.0 and TLS 1.1 are also checked in the Advanced Settings menu. I tried unchecking 1.0 and 1.1, but then I was unable to use the browser at all.
