v 18.104.22.16889 UI is sow and blocking compare to previous version
unsure what is causing this, but i find the new version to much less performant.
We’ve just released SQL Compare 22.214.171.12493 to Frequent Updates, which some performance improvements when selecting/deselecting large numbers of tables. The performance improvement is particularly noticeable when the source is a scripts folder and the target is a live database over a network connection. (SC-9157) Does this solve your problem?
