Password Manager ignores portal

[Eric the irritated]

I have Kaspersky Password Manager (KPM) installed on, and synchronised across, three devices: a desktop computer running Windows 11, a Samsung tablet TAB S9 FE+, and a Samsung phone model A53 5G. The Samsung devices both run Android. I need to frequently access a medical site, Myindici, which is installed on all three devices. KPM works perfectly on the desk top machine but does not work at all on either the tablet or the phone. I am most interested in getting it running on the tablet and I will be referring only to the tablet unless I indicate otherwise.

When logging to the portal for the first time KPM does not try to capture the login data.
When the login data is entered in KPM (either manually or by synchronising with the corresponding data on the desk top), when attempting to login, there is no transfer of the login data from KPM to the login screen. Even when the correct login data is entered in KPM, tapping  “Open in browser” on the tablet will only open the login screen without entering any data.

Why should this be happening?
