I have a similar issue with the favorites - both, using Android App and Firefox browser.
I use a manual timestamp on the favorite names in order to list them chronically. Unfortunately, my list is "full" now, since the latest favorites can not be edited anymore.
For me, it seems that favorites can be saved (so far without limit) but they cannot be edited since items with order >43 do not appear in the menu anymore. Thus, they can be found in the search list but then not modified.
Can anybody outline a workaround for this? Is there a fix planned?
Thanks for your assistance.
