Why do I get the following error message?
singlestore> set global data_conversion_compatibility_level='7.0';
ERROR 1231 (42000): Variable 'data_conversion_compatibility_level' could not be set because dev_platform.tags is sharded on computed column 'tag_name_lowercase'. Please contact technical support.

Changing the data_conversion_compatibility_level will affect the results of computed columns and could result in different sharding of a table.
It would be best if you dropped tables with computed columns before changing the data_conversion_compatibility_level value. Then you can update the value of data_conversion_compatibility_level and recreate and reload the tables.
We can not make live changes to sharded columns.
