Tabs do swipe along the tab portion and while full screen swiping is a big thing with all phones, that is usually reserved for the UI, not within every app… particularly when you have sliders and stuff that can be misinterpreted as a swipe.
Besides, I recall that there might be some tab changes coming along that might make this a mute issue?
I think the notification part is part of the Phone’s OS, not sure if Blynk can do much on that, but there has been talk about links, at least with Android.
