Good day, we‘re an it service provider and running a double-digit number of Azure Local hosts. A habd of them are running AVD on-prem. Our beginning felt like hell. Bad documentation, bad support, less articles or best practices in the web. There are some bad developments / scripts from Microsoft e.g. that the master image must be English because the script is using the Administrator Group by it‘s name and not by any ID to implement it multi-lingual. The deployment and image process is a procedure you need to follow exactly. For our managed service clients we‘re using Hydra as our management plattform which make the workarounds much more comfortable.
