Ultimately, it depends on the bank whether they approve the loan. The idea that is "floating around" here is that the notary confirms to the bank that the process has been submitted to the [FA]. Possibly, the [FA] can confirm receipt or that would also need to be provided to the bank. This would then show that you have provided everything necessary but are just stuck in the waiting loop of the [FA].
If that is enough to (partially) release the loan, you are rid of the problem – only the bank and notary can tell you if that works, but in my opinion, it’s definitely worth a try.
