[2021] Mobile Client Needs to Allow Reconnections in PVE Content

I've not played any PVP yet but am grinding out the labs encounters (which are really fun!). I have lost too many runs because I did not leave the app running in the foreground. Spending an hour building a ludicrous deck through several encounters only to lose because you take a 30 second phone call is devastating.

Potential solutions include: checkpointing at the beginning of encounters or allowing reconnects.

I suspect this is not a bug but simply a missing feature. If this is a bug and you are supposed to be able to reliably reconnect to a game even after several minutes of the game not being the foreground app, let me know and I'll file a bug report.

Edit: It takes around 3 minutes for my reconnect attempt to become unsuccessful. On checking my phone logs, my phone conversation was actually 2 and a half minutes. So my ask is that this grace period be extended indefinitely or for a considerable amount of time.
