Yes, you can switch between editions during your 15-day trial.
To switch editions:
Click the Profile icon at the top-right corner.
Select Try Other Editions.
Click Try Now

You can switch between editions even if you're using a paid version.
For example, if you're on the Standard paid edition, you can switch to the Professional edition for a 15-day trial—and vice versa.
Please note that, you can trial multiple editions, but the total trial duration across all editions is limited to 45 days.
After using up all 45 days, you cannot switch to any other trial edition.
You can switch back to your original paid edition anytime by clicking Switch Back to [Standard/ Professional].
