Hello there, @henningrst-gmail. I can see the urgency of getting this resolved.
Our engineers are still investigating to identify the root cause of this issue, so they can apply a permanent resolution. For now, we don't have a specific time frame for when is this going to be resolved. Rest assured, this is being taken care of. While they do, I recommend reaching out to our representatives again, so we can add you to the list of affected users. To reach them, you can check this article: QuickBooks Online Support.
In the meantime, you can use the WebConnect feature to upload transactions. For more information about this, take a look at this article: Manually upload transactions into QuickBooks Online.
Once bank transactions download, you can now start categorising or matching them to straighten out your books. After that, you have the option to do your regular bank reconciliation.
Thank you for your patience while we work for a fix. If you have additional assistance while managing your bank transactions, let me know. I'll be around to provide further assistance. Have a nice day.
