I run Excel 2016 for Mac, which I bought, rather than subscribing to Office 365, on a 2018 MacBook Air. I use macros and today the 'Developer" tab has disappeared from the toolbar. When I went to Excel>Preferences>Ribbon & Toolbar, I get the message that "This feature is only available if you haven an Office 365 Subscription". I don't have, or need one. Has anyone else come across this? I paid for my licence and when I did so, Excel included the Developer tab. Suddenly, it has disappeared (I can only assume that Microsoft has removed it) and it seems that the only way that I can access my macros is for me to pay for something that was part of the contract when I bought it. If the only way is to sign up for 365, then this is tantamount to extortion.
