I've been very frustrated trying to use connectors some of which are generally available... Yet they don't actually work.
Here is the list of a few connectors I know that are not working I would appreciate it if others can help add to this list.
Azure Cosmos DB
Office 365 Video
The current list of connectors is inflated and misleading. I realize the sentiment from this I did is negative but I am absolutely frustrated because as I recommend solutions to my clients I recommend them expecting powerapps powerapps to do what it is supposed to according to its documentation. Microsoft looks bad and I look bad when we go to build a solution that can't work. The number of connectors is inflated and fake fix it or remove it!
