Hello Leco,
I have found the root.... Internet access to Web CRM machine !
Summary :
We have install fresh CRM V9 -> V9.1.6.3 but on plateform very blocked : no internet on CRM machines...
=> And on Unified interface only => Some icons not display whereas these icons are present on Dynamics 365\CRMWeb\uclient\resources\images\ folder like chevrondown.svg
When i Ask to test this CRM web server machine with internet outbound (80, 443) : the issue is fixed !
And I tested on a CRM Lab : the same issue, with making shure to flush web cach....
In developper chrome mode (F12) : we see error like this :
"
y @ app.js?v=1.4.2976-v91onpremise:2904
2.js?v=1.4.2976-v91onpremise:1 Some icons were re-registered. Applications should only call registerIcons for any given icon once. Redefining what an icon is may have unintended consequences. Duplicates include:
GlobalNavButton, ChevronDown, ChevronUp, Edit, Add, Cancel, More, Settings, Mail, Filter (+ 1791 more)
o @ 2.js?v=1.4.2976-v91onpremise:1
"
It's very strange to have this issue when CRM icons are present on install folders !
Not possible to have CRM on prem without Internet so..... ok ...... add proxy project on server....
