WebSql iOS13 Support Removed, alternative solutions before to migrate
Yes the notes do say "not supported", but if you go to: Settings > Safari > Advanced > Experimental Features, there is a setting called ‘Disable Web SQL’ which is turned on so just turn it off, but I would eventually migrate away from it.
Yes you can.
Go to settings, click on safari -> advanced -> experimental features
Look for webSQL.
If you're using an iPad do everything I said above but it’s called disable ... SQL.
