I’ve just installed v18.104.22.168 from 13th November.
In sharepoint 2010 I’m seeing a “this took forever” message on the form overlay – it seems to be because I’m NOT using tabs. If I enable a tab then the form loads normally.
I had a different issue…previously created rule based tabs stopped loading (no ‘this took forever’ message). I reverted back to the previous version and the tabs load as expected. Info sharing only, I’ll wait for a future release.
