Description

Acrobat Reader seems to store only one page number.
When opening it tries to open all files with this same page number.
Reproduced with a second pair of PDFs (8 and 45 pages).

Preconditions

• Open PDFs from last session on Acrobat launch: enabled
• Restore last view settings when reopening documents: enabled

Steps to Reproduce

• Open two files as two tabs in the same window.
• File 1: Go to a page number > than max page number of file 2.
• File 2: Go to any page except the last one.

Example:

| File | Number of pages | Page before closing | Notes |
| ------- | --------------- | ------------------- | --------- |
| File 1 | 395 | 150 | 150 > 119 |
| File 2 | 119 | 10 | 10 < 119 |

• Make file 1 the active file.
• Close Acrobat Reader completely (Command + Q).
• Reopen Acrobat Reader.

Expected Result

• File 1: Page 150 is active.
• File 2: Page 10 is active.

Actual Result

• File 1 opens on page 150.
• File 2 opens on page 119 (last page of the file).

Variant

Same steps, but make file 2 the active file before closing Acrobat Reader.
The expected result is the same.

Actual result:

• Both files open on page 10.
