IRS2Go App Error "Information Does Not Match" After Triple-Checking My 2023 Joint Return Information

I spent hours making sure everything on my 2023 return was perfect but keep getting an error message when I try to submit. Already checked all the math, verified my SSN, and made sure all forms are filled out. I'm using the IRS2Go app to check my refund status by entering my information exactly as shown on my tax return. I understand this tool is updated no more than once every 24 hours, but I keep getting a "Refund Status Error" message saying "Information does not match. Please reenter your information." I've tried multiple times and I'm still getting the same error. I filed as Married-Filing Joint and I'm positive all the information I entered matches my return exactly. I've triple-checked my filing status, SSN, refund amount - everything. Could this just mean the system is backed up and my file is pending? Anyone else getting errors today? I'm really frustrated after spending so much time making sure everything was perfect on my return only to be stuck on this error screen. Is the IRS2Go app having issues, or is there something I'm missing?
