Fell short with BOI any luck with haven ?

Has anyone recently been approved for a Haven mortgage after falling short with BOI?
BOI wouldn’t accept all of my shift allowance when assessing my income, which left me €1,500 short of what I needed to qualify for the First Home Scheme.
I’m wondering if anyone has been in a similar situation with BOI but then applied to Haven and was approved, with Haven accepting more of their shift allowance/income?
Would really appreciate hearing from anyone who has gone through this recently.
