Lightroom on iOS has an option to "Enable Lens Corrections," but has no provision to select a specific profile. Please add this capability, which is already on Lightroom for Web, as well as the Desktop and Classic applications. Lightroom for Web is a partial workaround, but is not useful if you are traveling and don't have a sufficient connection to be able to sync your photos to the web.
This became critical for me as I was struggling with this issue, for which the workaround for a faulty new lens profile was to change to an earlier version of the lens profile:

Here is what we have in Lightroom for the Web:
