1. In PT 1.0 it is possible to re-send a payment link for unpaid invoices, do we have the same feature on PT 2.0 ?

Yes you can re-send a payment link (if expiry was not set); create a template invoice which can be used/reused; set activation date when the link becomes active; set expiration date when the link expires.

2. In PT 1.0 the generated report could be in PDF format, organized in a good layout, Does PT 2.0 also have this capability? 

There is no PDF generation option currently. 

As a workaround solution, within Excel 

(a) No page formatting - Save file as and choose PDF format 

(b) With page formatting – Page Layout, Set the formatting of margins, page size, etc. Save file as and choose PDF format.
