Not sure why but keep getting logged out this afternoon from print shrimp, anyone else?

For the bulk listing, for each bulk can it only be under 1 template, or can you use multiple templates in a single bulk ? (if that makes sense?) if it doesn't make sense here is me trying to clarify further haha say you have 2 templates of 2 different styles of posters, can you use those 2 templates at the same time and select which uploads are going to be for which template? or does the bull listing only work with 1 template at a time?

If using variations of the same design but different styles, when naming should I start with the style or the location for travel prints? If it is by the style, then when listen alphabetically, the styles will be grouped together, and if done alphabetically by location, then the styles of the same location will be next to each other which would be better?

Is this the correct one to use for everything other than the uk when setting up delivery options in etsy?

When editing in different sizes, is it best to do it in the largest size in its group (e.g. A0) so then it is easier to scale down?
