I ended up playing around with the app for a while after everyone had gone to bed. I managed to get it working. I found one question on the apps faq page well & truly hidden that gave me a clue. In the end, the fault wasn't with unRAID (which I suspected anyway), it was poor documentation, the lack of a good setup video, and operator error.

I'm finally circling back around to this. I've now completed the Disk 1 upgrade and it's all gone well.
 
I also got to re-run the test that caused the initial issue that lead me to raise this thread in the first place....I transferred a (roughly) 25GB file from my PC to the server. This time the file transferred without any issues. It did slow down a little - which was expected given I'm not using a cache drive (yet), but the transfer speed never dropped below 50MB/s, which is WAY faster than it ever went before.
 
So, I'll mark this thread as solved. I believe - based on many of the discussions that have gone into this thread - that the cause of this issue is one of, or a combination of, these 3 things...
The problem share used the 'most space available' allocation option. I'm now using the 'high-water' option My server was running a bit low on storage space. I've updated one of the drives the share was using (from 4TB to 12TB) My server still uses the 'reiserfs' file system. The drive I updated now uses 'xfs' instead Thank you to all who contributed to this conversation, helped me to learn a lot, and finally resolve the issue. I'm grateful.

UnRAID Support acknowledged and responded to my issue. They confirmed the replacement key did go through, but so far no clues as to why I didn't get the original replacement key email. I did ask the question, and I'll post back here if they respond.
