I find it totally unacceptable that Microsoft would knowingly allow this flaw and wash their hands of all responsibility by just putting in documentation �It breaks sometimes and ignores all the work you�ve done�. In a case I experienced it shook confidence in the system as back end processes were much less trusted by end users as they had these imports just fail, losing significant work, and this massively affected user opinion of the system. I was forced to minimise automation within the system as it was no longer considered reliable. Obviously I knew that it was limited to Excel Online, but less informed decision makers didn�t accept this. This obviously devalues the system and directly affects my clients opinion of me, which I do not appreciate.
