I tried Panda on My MacBook Pro(15 inch 2017), macOS 12.3.1 with Panda 1.0 (2595) located in my Applications Folder.
On this machine no problem: the link was created as expected, and functioned ok.
I also tried to make the same link on my iPhone 13 Pro Max and my iPad Pro 12,9 2021, both with iOS 15.4.1.
I started Panda on both from Testflight, Panda Version 01 (2801).
I created a new document on my iPhone and a new document on my iPad (not on iCloud)
When I tried to make the link from the Panda Keyboard the app crashed directly on iPhone and iPad.
When I made a table first and then created a link in the table, the link was created as expected.
