The dedupe app/extension works wonderfully for me, except whenever I select a field of type “checkbox” i.e. a Boolean, in the record to be deleted, then the merging still happens but there is an error message and the base has to re-load for about 30 seconds. This gets annoying if there’s a handful of records or multiple Boolean fields. And means I have to go through manually checking the newly merged record in case anything crashed in the process whilst page was refreshing.
