One more thing.
When using a larger vault on mobile, things can get sluggish (performance is of course proportional to how many plugins are vying for resources). What I found is that keeping two profiles (the secondary one can even be the exact replica of the primary one, so you can copy-paste stuff and rename the dot folder which you can relaunch with) is a good idea, regardless of whether one wants to use DataView or not.
This might have something to do with how cache files are accessed by the app. (I am on a jailbroken device and can remove the cache folders and re-index, but that doesn’t solve things for long; employing this alternate use of profiles can come with a performance boost as I’ve experienced just now again.)
This trick seems to have some sort of refreshing effect and can be used when a simple restart of the device doesn’t help.
