Hi all. Yes, as @TiroliTemar said, the Free plan is not the same as Free Trial, and due to the limits, only 1 branch is available for this subscription tier. With proper management, this should be enough to work on simple projects. Here you can read more about Version management → Version Management | Crowdin Documentation
If you need more branches, I’d suggest you check out the Team plan, which offers unlimited branches → Plans, Pricing, and Free Trial | Crowdin
Alternatively, you can apply for open source license (unlimited branches as well) → Open Source License Request Form | Crowdin
