No iPad or iPhone backup since current build of iOS app

Just discovered that my iPhone 8, iPad Pro (9.7”) and iPad AIIR 3 have not done backup since I installed the current build of the app about a month ago. They are are set up to backup whenever on wifi, but this is not happening.
Also just noticed it is possible to to have back up tasks to cloud, pc and NAS simultaneously - obviously I have not been paying attention.

Ekaterina, is there any progress of fixing this issue? It has been over 2 months since it was first reported. None of my iOS devices are backing up.

I suspect that the problem was with the iPad/iPhone firmware. Since updating to iOS 14 backups occurring as they are supposed to. My iPhone 8 which has been refusing to update firmware for some months is still not backing-up.

Update: The iPhone 8 all of a sudden decided that it would install iOS 14, and it seems to be working now for the iPhone as well.

I wrote another comment about this in another thread younger than this one. I detected that there is some kind of error at least in the Qnap NAS version of the acronis true mobile server and how process the calendar data to backup. It is possible that the client has a new version of the API and the NAS software is not updated yet (I don't know). The log in the NAS is related to validate a datetime value as far as I understand. I can't follow it without the original source code. The log says:

There is some data with datetime that is not managed well by the server and comes from the calendar of my iOS..

More than one years has passed since the issue was discovered, and still no solutions?

First, it is my understanding that backup NAS devices is no longer supported by the iOS apps. So if that is your problem, you are out of luck.
My backups to the clouds still not as reliable as I would like. On some devises there are major gap - but they are rarely used so that may be a partial explanation. My iPad air which gets heavy usage seems to update regularly, sometimes twice a day. I suspect an algorithm is used to decide if a backup is required - monitors the various types of data to be backed up to see if there are any changes.

Ian is correct, the support for mobile backups to NAS devices has been discontinued 69362: Acronis Mobile: sunset of mobile backup to NAS
