Hello @mauriciosti thanks for letting us know and for creating an issue on the github repository. I will try and look into this and get back to you.

@TrystanLea I’ve updated this issue with a little detail.

Not sure it’s particularly helpful but I’m happy to work with you to sort the problem, if that’s of any use.

@mauriciosti - @bwduncan and I have been working on this issue and have what we believe may be a solution…

… but it would be good to have some more people test it out. Do you still have the problem and, if so, could you trial the fix for us?

Thanks.
