DAE have problems with ACH transactions at Amplify Credit Union?

Since I opened my account a few months ago I have had so many problems - Amplify being unable to send me their own security codes, third parties not recognizing the bank or its routing number, and inability to complete ACH transactions.

The most recent issue is that a third party recognizes the bank, but says “there was a problem processing” the transaction. Luckily I have an account at a different bank and was able to pay them.

What can I do to get this resolved? I see a lot of good reviews for the bank but haven’t seen any reports of this issue, but surely it can’t be just me? Did I make a mistake opening this account with them?
