Since Internet Explorer is EOL we have configured most of our LOB apps including SRM OCI Punch out shops to work in Compatible mode by adding respective shop urls it to the IE Mode list. This will ensure business continuity whiles we look for a long term solution. Upon doing this we stumbled upon a problem i.e. seamless login doesn't seem to work in Edge chromium even though the site renders as expected after configuration. The sites keeps asking for username and password or credentials are not working even though when reproduced in IE works as expected.
After inspecting the session traffic via Edge F12 tools could it be that it is not possible to share session cookies ids etc. between IE and Edge until you instruct both browsers to do so in the configuration file?
Will there be a need to add snippet in the ie--mode .xml file instructing both browsers to allow this or configured via the Server or SAP backend? Recommendations and workarounds will be appreciated.
