2.5 year family visa renewal coinciding with work sabbatical

Hi all,

I'm an American, and my first 2.5 year family visa renewal is due in January 2027. My spouse and I both work full time in the UK, and we meet both the income and the savings requirements. We'll be applying from the UK. My spouse will be taking a sabbatical from work in November, December, and January coming up to finish their master's degree. We'd like to apply in early December so we have some wiggle room in case we hit a snag.

In addition to other required documents, for financial documents, we're planning on including:

* They get paid in November for October, so proof of six months of income * 6 months of income for me * Letters from both of our employers confirming employment * A letter from us explaining the sabbatical * A letter from their employer confirming the sabbatical and explaining that their employment will resume in February unchanged * Bank statements for both of us for the months corresponding to the proof of income, proving that we meet both the income and the savings requirements

Or, instead, because they get paid in November for October, should we avoid explaining the sabbatical at all, and proceed as if it wasn't happening?

Does this sound sufficient? Should we be concerned that the sabbatical will cause problems? Is there anything you think we're missing?

Thank you so much for your help! It's very much appreciated!
