Firmware 3.1.33 broke app

After latest firmware update from yesterday the app can no longer operate AC units. The old app Daikin Controller still works and shows the version is properly updated so this is very likely an issue with Onecta.
Following the steps from the developer comment to this review has resolved the issue for me.

Developer Response ,

We are sorry for the inconvenience and are aware of the issue. We are working to resolve the issue as soon as possible. A status page is available at where you can follow our progress. We have indicated some possible workarounds that should fix the issue till we have a final solution available.

Cannot update firmware

Updating Air Conditioner firmware with this software is a nightmare. One has to be connected to the home Wi-Fi to begin, then it fails. We need to switch to DaikinAP, otherwise it won’t accept firmware updates. But then the iPhone is offline so it can’t download firmware. The trick is to switch between these two until the update succeeds which may take hours in multiple attempts. Finally the DaikinAP remains active with no obvious way to disable. So we need to reset Wi-Fi settings on the AC unit, then reconnect again, which brings DaikinAP up again, but now ONECTA shows the units as offline and offers to connect them to the cloud. Once this is done, DaikinAP is finally turned off. Whoever designed this behaviour needs to get stoned. It has been like this for each update ever since I bought the two Prefera units one year ago.

Not recommending it to friends

I am not recommending Daikin to my friends that will buu air conditioning units as I am so disappointed and frustrated with the fact that even after the last update of the application I still don’t have the function Powerful mode showing in it. My air conditioners have the functionality , the remove control has special button dedicated for it , but not in the app. I have written multiple emails to the support team - 0 response, so bad customer service experience!
