Covering the charges for the next 31 days is nice but mine already charged me a week ago. This also seems like a bit of foreshadowing in terms of how long this is actually going to take. We have no idea though, because nobody will give a timeline. Either way, looking forward to tomorrow.
Although it doesn't help you already being charged, you'll still get your 31 days free right after your current paid month ends - so you won't see a charge next month if that helps.
In terms of the timing of the 31 days, we picked this amount of time purely for peace of mind we hope it offers compared to something shorter. There's no relation to timelines or anything.
