They seem to have been silent on the migration issue (on the live status page at least) for nearly 24 hours, very bad practice.
madwoman, is the iPad looking at a different budget file? I have had problems (relatively often, actually) with Dropbox just stopping sync, but in that case the difference is that the Macbook is more up-to-date than the phone, not that the file just looked crazy.
I can't find any way round the problem of not starting the month with a full month's expenses on hand already, other than putting all the income in uncleared on the first of the month. The only other way I can think of doing it, again using a kludgy off-budget account, is to 'loan' your budget a full month's expenses at the start of the month, then as your pay cheques arrive, you transfer them back out to the loan account, aiming to leave it at slightly more than zero, which is you building your buffer slowly but surely. I still can't work out if I mean off- or on-budget, will have a play. Or as the pay cheques arrive, keep changing the value of the fake loan on day 1, until you can eventually make it zero by the end of the month, and then delete it when you reconcile the account.
Where you've got a future-dated expense, you can put this in and it will be taken account of in the 'inspector' window on the right hand side, I will do an Evernote showing this.
The bank links aren't applicable to us in the UK anyway, unless you (a) have a NatWest account and (b) you want to give all your security details to Finicity, almost certainly in breach of the Ts and Cs of your account.
I can't see anything changing about nYNAB and the handling of the lack of income on day 1 of the month. In essence YNAB 4 didn't encourage you hard enough to buffer, although again I wonder whether it will become too daunting if people have got to budget every time a pay cheque arrives, or create some horrible workaround that could go wrong. I don't like the answer "make everything a setting" but here I can see a case for 'strict YNAB' and 'loose YNAB' (maybe with some kind of indicator at the top showing you're not following rule [x] as an incentive to get there).
I think I understand the handling of credit cards now, although I think it is very confusing to regard it as another category yet it isn't actually budgeting the money twice.
