Zoho Expense suddenly not working on iPhone X Max

Zoho Expense suddenly not working on iPhone X Max

With the last app update -- which it appears was 3 days ago -- Zoho Expense no longer works on my Apple iPhone X Max. (7 year old phone)

I updated both the phone AND Zoho Expense -- and when I click on it...it starts to open...then just disappears. It won't open.

So I'm wondering if perhaps it's not being supported on iPhone X anymore?

Appreciate any help anyone can provide!
