I have some custom views built for Panel that look at file path in the Categories.  For example:

listItem([Filename (path)],4,\)
Then:
Regex([Filename (path)],/#(\d{4}-\d{2}-\d{2})#/,1)
and then:
regex([Filename (path)], /#\d{4}-\d{2}-\d{2}\.(.+?)\.flac\d+#/, 1)
and then:
removeright(ListItem([Filename (path)],math(listCount([filename (path)],.)-1),.),1)

My file path (on my windows server is this: G:\Shared drives\Music\verified\2019\dmb2019-09-10.dpa4028.flac24\dmb2019-09-10t01.flac).  When I view this in Panel (connected to my server), I'll have choices like this:

2019 > 2019-09-10 > dpa4028 > flac24 > FLACs show up.

But when I use MC on Android, my expressions don't work the same and I see:

2019 > Unassigned > Unassigned > flac24 > FLACs show up.

An easy answer is that I should add these things as custom library fields at import instead of relying on filename path.  I'll probably do that because I imagine the views will be faster to load as well.  But if the first and last items work to show me '2019' and 'flac24', why wouldn't the second and third work?

Because the two failing expressions use Regex, and the two working ones use MC expressions?

It sounds like Regex isn't implemented in JRiver for Android.

That makes sense... My initial thought was that the [Filename (path)] must be somewhat different between Windows and Android, but was confused why it was working for some.
