Hello Snarksu,
Thank you for reaching out and sharing the details of your experience with Microsoft Lists I completely understand how frustrating it can be when a tool you rely on heavily for your work suddenly feels less intuitive and limits your workflow. Your concern is absolutely valid because these changes can significantly impact productivity and the way you manage large sets of data.
The recent updates to Microsoft Lists introduced a new form experience that connects form creation more closely to list columns. While lists can technically support thousands of columns the practical limit is based on the row size restriction of 8,000 bytes per item. This means the number of columns you can add depends on the type of columns used. For example simple Yes/No columns consume fewer bytes than text or choice columns. In SharePoint Online this usually results in a maximum of around 250 to 300 columns before hitting the limit. The behavior you’re seeing at around 303 columns aligns with this constraint rather than being a bug. To work around this you might consider restructuring your list by splitting it into multiple lists or using related lists with lookup columns. You can also explore Power Apps or Power Automate for advanced form scenarios if the built-in form functionality feels restrictive.
Could you share what type of columns you are adding and whether all of them are required in a single list?
I hope this answer is helpful if you have further questions feel free to reply back
Regards,
Marcelo
