Transferred as it's not an appointments issue but a profile one.

When you say a new session, do you mean a non-logged in browser window?

Also, do you have any non-default shareapi_* parameters active?

./occ config:list core | grep shareapi

I think there may be some weirdness around here with the instanceof IUser checking below so low:

server/lib/private/Share20/Manager.php

Lines 1976 to 1992 in 39a7166

	public function currentUserCanEnumerateTargetUser(?IUser $currentUser, IUser $targetUser): bool {
	if ($this->allowEnumerationFullMatch()) {
	return true;
	}
	if (!$this->allowEnumeration()) {
	return false;
	}
	if (!$this->limitEnumerationToPhone() && !$this->limitEnumerationToGroups()) {
	// Enumeration is enabled and not restricted: OK
	return true;
	}
	if (!$currentUser instanceof IUser) {
	// Enumeration restrictions require an account
	return false;

We call the above from here:

server/core/Controller/ProfilePageController.php

Line 98 in 39a7166

if (!$this->shareManager->currentUserCanEnumerateTargetUser($visitingUser, $targetUser)) {

But some further digging will be required.
