You may try a downloaded browser, they likely ship with a newer version of webkit than what’s on the system or in the store but I’m not 💯 and Google didn’t reveal any clarity on the matter.
Imo backend FOSS needs a complete rethink with an easy way to manage one’s own digital stewardship. I’ve lost a ton of data to FOSS projects (masto, lemmy, etc) just because the random host I chose decided to close up shop. Not particularly the fault of the software vendor per sae, and while I do not wish to hassle with hosting my own entire instance I’d be happy paying for or hosting my own data.
Perhaps an invalid opinion, but a bug report that falls outside of scope because of lack of detail or lack of reproduction is still a valid bug report for metrics and general user experience imo. Could lead to interoperability efforts, user experience recommendations, user education utilities, or a bug getting patched but the end result is always the same: a better experience for the end user.
