Technology Changes, this is a constant.
That said, our testing shows that Call Steward is compatible with the following browser versions.
Safari 10.12 Mac OS 10.12/ Seirra
iPad Mini 4 Safari 11
Kindle Fire Silk 79 (not regularly tested)
If you browser is older than these, there is no guarantee that you will be able to login.
Also please note that INTERNET EXPLORER, any version, is not on this list.
We are working on those compatibility issues.
