Random lag and app disconnects on mobile data, device issue or network setting?

Hi everyone,

Lately I’ve been noticing random lag and short disconnects when using certain apps on my phone, especially when switching between Wi-Fi and mobile data. Some apps pause, reload, or lose session data, which makes me wonder if it’s a network handoff issue, background data restriction, or something at the device level.

I ran into a similar situation while testing a hub script setup, where short drops in connectivity caused scripts and sessions to reset, so it made me think the same kind of network behavior could be affecting regular mobile apps too.

Has anyone here seen this with telus mobile devices? Do you usually look at apn settings, battery optimization, or network mode when troubleshooting these kinds of dropouts?
