Slow TV Show open with SQL since Jarvis (16.1)

Hi All,

I use a ReadyNAS running SQL for my Kodi database (have done for 5+ years without issue) with various devices around the house. Openelec, Windows 10 & Amazon Fire TVs.
Everything working perfectly until I upgraded to Jarvis (16.1).

The issue I now have is that when I click on a TV show it takes ages to open. Its in the range of 15-20 seconds where I get the “working” icon down in the corner. Weirdly, once I’ve opened the show, the season folders themselves open immediately and when clicking the files, they also open immediately and play normally. Everything else works perfectly fine and playback isn’t an issue. Its literally just this weird tv show folder problem.

Its not a major problem but its VERY VERY annoying and as its only just happened immediately after the upgrade, its clearly some change introduced with Jarvis (I was on Isengard prior).

I can grab a debug log but just wanted to see if this was a known issue first.

I found an older thread that shows similar symptoms but this was back in 2014/gotham days so not exactly the same. http://forum.kodi.tv/showthread.php?tid=212116

Any pointers / advice would be very much appreciated.
Thanks for reading.
