I would just add …
#2. You may find reading through these at least somewhat interesting,
But yeah long story short, currently not a good workflow.
#4. You can manually implement any CMS, Form sending, etc., that you like by using each setup and usage criteria set forth by the 3rd party library, service, etc., that you wish to use.
Otherwise overall, unless some things change regarding either app heading into the direction of the other, you may need to keep your current workflow that you previously discussed regarding using - Pinegrow (+) Wappler, for perhaps the foreseeable future.
Thanks for sharing Pinegrow love over there also.
