# Experience review

In general, we've had some issues completing this training, but overall it tooks us 1 hour to complete so it wasn't bad.

## What made you smile?

* The time from commit to deploy to check changes on preview was fast


## What did you find confusing?

* In documentation (https://beta-docs.redocly.com/author/how-to/versions/) in example we are missing `yaml` files with OAD
* Issue with `ghost text` when deleting characters in editor
* It's not straighforward to copy & paste multiple files (from `v1` to `v2` folder)
* In WYSIWYG we have `Mobile view` button, but it contains `Desktop` views as well
* We've made editor crashing, when playing around with `sidebars.yaml` and `versions.yaml` file.
* Somehow, during reload of page (after editor started to work very slowly), we have lost content of `versions.yaml` file (it was still possible to revert it and restore data).
* When working on Museum API `sidebars.yaml` WYSIWYG was showing us `Kitechen API` page
* Initially we've had broken links in `sidebars.yaml` inside Museum API folder, which resulted in empty pages (no OAD pages available). We didn't see any error related to it and it took us a while to fix paths and get expected result.
