The application is custom made for Huawei, a special version of Office 365. It's not fully open to 3 Cloud or 365 because at Huawei, we have some restricted tools within Office 365. We use them just for email, Word documents, etc. We are not able to download or use online templates or download anything from Cloud. All those features are restricted. We're using only what Huawei provided as tools.
It has been fine regarding stability-wise issues, technical errors, and downtimes, but with Microsoft there are sometimes bugs, freezing, re-downloads, or redos. They have to reload the restrictive features and license. There was an issue from my PC itself, but the good thing is they auto-recover and auto-save, so when corruption happens, we can retrieve the latest version templates from Word, Excel, or PowerPoint.
Sometimes I use templates from different versions through copy-paste. When I want to save, I get prompts about text or fonts. I need to click again and apply something to be able to save the file. When I have different styles, it is very hard to track this. To avoid checking these optics every time I want to save the file, sometimes reason pop-ups appear when saving files, indicating projects have some strange text.
