On master (124e75a41ea0f3f0e90b63b0c41813184ddce2ab), Transifex translation check fails for https://github.com/bitcoin-core/gui/blob/124e75a41ea0f3f0e90b63b0c41813184ddce2ab/src/qt/forms/intro.ui#L206 with a message:
The expression ‘%2G’ is not present in the translation.
In “Organization Settings” –> “Translation checks” I have changed the status of the “Variable substitution specifiers (like “%s”) are preserved in the translations.” check from “error” to “warning” temporarily. This setting should be reverted after applying this PR change.

I faced the same issue while working on Ukrainian translation.
