I recently scheduled a transfer that would surpass my daily limit, and would therefore be unlikely to go through when the time came. Yes, I probably should have been more aware of my account limits, but it would still have been helpful if there was a warning upon scheduling.
In this particular case, my payment even surpassed the maximum daily limit so I feel it should have been impossible to even successfully schedule it.
Luckily the bill was not due immediately, so I could spread out the payment over multiple days. But it was still an unwelcome surprise.
TL;DR: warn when scheduling payments that are likely to fail due to daily limit restrictions.
