I need a quick and simple solution to this problem as I hope to go live with the site next week. I think that the problem is related to Babel.
Please do not bid for this project if you cannot do it. Before I approve your bid I also need to see at least two Ionic 4 websites of yours that are doing well in Google and have more than one page indexed in Google. If you think that this can be solved but will need more work then please add the bid for the extra work to your comments.
