It’s been like this for years.
Airtable doesn’t care.
I recommend using Excel in iOS. With mouse support, macro, pivot table etc support, it’s better than Airtable.
Maybe so, but seeing that this thread has been opened since 2017 and no fix, it is very likely Airtable will not do anything.
Enterprise customers that uses Airtable use laptops more often than iPad / iPhone as their primary work device.
Column adjustment is important for a spreadsheet-like application!
Excel have this and so are all the other 3rd party Excel-compatible iOS application.
