App becoming non responsive & crashing on iPad

Hi there, hoping to find some advice. My partner and I both use the Aloha browser and vpn regularly but yesterday my partner’s app developed an issue out the blue. It began to randomly freeze up, nothing would respond at all, and then the app would crash. She would have to restart it manually and the browser would then load back up, but as soon as the page loads it becomes unresponsive again. This has happened on multiple pages and tabs so it’s not a single website causing problems. This is happening without the vpn being on, the browser isn;t functioning long or well enough for her to even switch that on.

Initially she tried closing tabs and restarting her iPad. She reinstalled the app this morning but it’s still happening. Her iPad didn’t update anything or install anything prior to this happening. Any ideas how to fix this issue? Would be extremely grateful for your help.

Thanks.
