I recently upgraded to Premiere Pro / Media Encoder 2021. However, Media Encoder will no longer recognise the 'Use Previews' function when encoding timelines from Premiere Pro.
Now, each time I send a project to Media Encoder (or Export it from Premiere Pro), it ignores the Previews completely and re-encodes each sequence, taking much longer to encode a file.
I’m encoding a DNxHD 1080p timeline into h264. Same as I’ve done for years and it’s always used the previews when asked, no problem!
Troubleshooting steps so far:
I have updated my GPU card driver with a clean install
I have fully uninstalled all 2020 versions of Premiere / AE / Media Encoder
I have cleared my Media Cache
I have deleted Previews within the project and re-rendered
I have started a new project and build a sequence within that
I have updated to 15.1 on Premiere / Media Encoder
Despite all of this, the problem remains.
Using Task Manager in Windows, I can see that the hard drive that hosts the preview files (E:/) isn't being accessed during encoding at all and that the GPU is doing lots of work. Usually, when using Previews to encode, the GPU does practically nothing as it has nothing to render.
Also, the readout on Media Encoder shows 'Hardware Encoding' when usually with a fully rendered project it will show 'Software Encoding' by default. When I try forcing Software Encoding, it stills ignores preview files.
If anyone has any other ideas that would be highly appreciated!

It seems that by unchecking 'Import sequences naively' have fixed this problem. A 30 minute, 1080p fully prendered Premiere Pro sequence now takes approx 5 minutes to encode into a H.264 (as opposed to 2 hours+ before) I previously had the 'Import sequences naively' checked to ensure captions were sent to Media Encoder, so will see if that is still the case now....
