Thanks!
If you've installed everything in the last 6 months with the pretokenised option enabled and up to date firmware then there's no need.
But it shouldn't hurt to click 'Reinstall apps' (which should keep existing apps' data but will re-upload everything else). It doesn't hurt to do a backup first just in case though!
I just added a bit of info on what I mentioned above in https://www.espruino.com/Bangle.js+Performance - so if your Bangle is running slow then that might help you to figure out what apps are causing it!
