Hi, Spoofy,
the Brother MFC-L3780CDW is not on the Mopria List, either, which is my printer.
If you read my long post directed at you, Spoofy, I explained how I solved it by re-installing Windows starting with Windows 10, first.
But, if you work at Microsoft or talk to them on those developer teams, can you please pass on my concerns. Nobody ever acknowledges feedback or responds. You don't even get a confirmation email. It's like nobody cares and nobody ever does anything about it when you do post feedback.
My two issues are "Scan to PC" and the other one with MIcrosoft 365 EDITOR which has no OFF switch to turn off the spelling and grammar checker in WORD and Outlook.
If this bug is going to take a few months to resolve and you feel it is important to modernize it, then, why can't you at least post the download to the pre-24H2 update on the Microsoft site or send an update that makes it possible to roll it back until you fix the issues?
It's like nobody cares. The only download on Microsoft's site is of Windows 24H2 and most people have Windows Home, so, we don't have the Policy Editor in Windows Pro or a way to go and un-install 24H2 if it already installed on the computer and not everyone has the time or the knowledge to even do a complete Windows install from scratch and have to re-install your programs. It's so disruptive.
It's like Microsoft is working for itself and does what it wants when it wants and nobody cares about the customers. What of a small business with 5-people in an office on a small network who suddenly can't do Scan to PC for 2-3 months or indefinitely.
