Hi,
You need to ensure that you've replaced '«' with 'Previous' in the following locations in your Pagination Web Template:
{% if current_page == 1 %}
<li class="disabled"><a href="{{ request.url | add_query: 'page', '1' | path_and_query | escape }}">Previous</a></li>
<li class="disabled"><a href="{{ request.url | add_query: 'page', prev_page | path_and_query | escape }}">Previous</a></li>
{% else %}
<li><a href="{{ request.url | add_query: 'page', '1' | path_and_query | escape }}">Previous</a></li>
<li><a href="{{ request.url | add_query: 'page', prev_page | path_and_query | escape }}">Previous</a></li>
{% endif %}
Once that's done, you need to clear your portal cache by either going to /_services/about as a logged in user with the Administrator Web Role, or, by heading to the Power Apps Portal Studio and using the Browse Website button.
I've just tried this with no issues.
Thanks,
Aaron
