Mandrillapp security error

This didn’t seem to happen last week, but as of this morning, upon launching the AppSheet install invite from an email in the Android Gmail App, we are getting the error:

Attackers might be trying to steal your information from mandrillapp.com
NET::ERR_CERT_AUTHORITY_INVALID

This only happens from Android phones, we can still launch it from our Windows machines from Gmail in Chrome just fine.

Can we fix this from our end, or is there some server issue with AppSheet?

Hi @Greg_Pommen, if you try opening Gmail in the Chrome browser on the phone and follow the link from there, do you see the same problem? Can you check whether there are any updates available for the operating system, Chrome, Android System Webview or the Gmail app?

Also if you choose Advanced or Learn More is there any more information about the specific certificates involved?

Hi,

This only happens from Android phones, we can still launch it from our Windows machines from Gmail in Chrome just fine.

Our phones are up to date, no updates are pending. Samsung S9 Galaxies.

This is the message when I tap Advanced:

Do you see the same problem if you try to open mandrillapp.com directly in the Chrome browser on the phone?

If I keep ignoring the security warning about mandrillapp.com in Chrome, on the phone, a couple of times, and keep opening the unsafe links, it does open the app finally.
