dbcc checkdb in azure managed instance error, The database snapshot for online checks could not be created

[pixies386]

we are using EXECUTE dbo.DatabaseIntegrityCheck @databases = 'USER_DATABASES', @CheckCommands = 'CHECKDB', @LogToTable = 'Y',
it runs DBCC CHECKDB ([databasenameX]) WITH ALL_ERRORMSGS for all db
but in an azure managed instance is failing, in some databases.
"The database snapshot for online checks could not be created"
we have read that azure MI doesnt support database snapshots, but some databases doesnt thorow this error.

Have anyboy experienced this problem? we have seen that with tablock can be used to avoid using database snapshot but it is not optimal because of the locks it impose on database and tables.

thank you
